○ | ○ | Article | Countering Malicious URLs in Internet of Things Using a Knowledge-Based Approach and a Simulated Expert | This article proposes a novel methodology to detect malicious uniform resource locators (URLs) using simulated expert (SE) and knowledge-base system (KBS). The proposed study not only efficiently detects known malicious URLs but also adapts countermeasure against the newly generated malicious URLs. Moreover, this article also explored which lexical features are contributing more in final decision using a factor analysis method, and thus help in avoiding the involvement of human experts. Furthermore, we apply the following state-of-the-art machine learning (ML) algorithms, i.e., naive Bayes (NB), decision tree (DT), gradient boosted trees (GBT), generalized linear model (GLM), logistic regression (LR), deep learning (DL), and random rest (RF), and evaluate the performance of these algorithms on a large-scale real data set of data-driven Web applications. The experimental results clearly demonstrate the efficiency of NB in the proposed model as NB outperforms when compared to the rest of the aforementioned algorithms in terms of average minimum execution time (i.e., 3 s) and is able to accurately classify the 107 586 URLs with 0.2% error rate and 99.8% accuracy rate. | Anwar, Sajid; Al-Obeidat, Feras; Tubaishat, Abdallah; Din, Sadia; Ahmad, Awais; Khan, Fakhri Alam; Jeon, Gwanggil; Loo, Jonathan | Inst Management Sci, Peshawar 25000, Pakistan; Zayed Univ, Coll Technol Innovat, Abu Dhabi, U Arab Emirates; Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu 41566, South Korea; Univ Milan, Dipartimento Informat, I-20133 Milan, Italy; Xidian Univ, Sch Elect Engn, Xian 710071, Peoples R China; Incheon Natl Univ, Dept Embedded Syst Engn, Incheon 22012, South Korea; Univ West London, Sch Comp & Engn, London W5 5RF, England | Khan, Fakhri Alam/GPP-4180-2022; Din, Sadia/ADU-4679-2022; Ahmad, Awais/AAA-4504-2019; Loo, Jonathan/E-6075-2019 | 59138451900; 35785711700; 6505939854; 57188997144; 57224336715; 24474801200; 15022497800; 36652697900 | sajid.anwar@imsciences.edu.pk;feras.al-obeidat@zu.ac.ae;abdallah.tubaishat@zu.ac.ae;saadia.deen@gmail.com;aahmad.marwat@gmail.com;fakhri.alam@imsciences.edu.pk;ggjeon@gmail.com;jonathan.loo@uwl.ac.uk; | IEEE INTERNET OF THINGS JOURNAL | IEEE INTERNET THINGS | 2327-4662 | 7 | 5 | SCIE | COMPUTER SCIENCE, INFORMATION SYSTEMS;ENGINEERING, ELECTRICAL & ELECTRONIC;TELECOMMUNICATIONS | 2020 | 9.471 | 3.4 | 0.92 | 2025-06-25 | 10 | 20 | Uniform resource locators; Feature extraction; Radio frequency; Classification algorithms; Phishing; Blacklisting; Internet of Things; Feature extraction; malicious URLs; naive Bayes (NB); simulated experts (SEs); URL classification | STATIC CODE ATTRIBUTES; PREVENTION | Feature extraction; malicious URLs; naïve Bayes (NB); simulated experts (SEs); URL classification | Decision trees; Deep learning; Internet of things; Logistic regression; Trees (mathematics); Factor analysis method; Generalized linear model; Knowledge base system; Knowledge-based approach; Lexical features; Novel methodology; State of the art; WEB application; Knowledge based systems | English | 2020 | 2020-05 | 10.1109/jiot.2019.2954919 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||

○ | ○ | Article | Dynamic Power Splitting for SWIPT With Nonlinear Energy Harvesting in Ergodic Fading Channel | Simultaneous wireless information and power transfer (SWIPT) is very promising for various applications with the Internet of Things (IoT). In this article, we study dynamic power splitting for the SWIPT in an ergodic fading channel. Considering nonlinearity of practical energy harvesting (EH) circuits, we adopt the realistic nonlinear EH model rather than the idealistic linear EH model. To characterize the optimal rate-energy (R-E) tradeoff, we consider the problem of maximizing the R-E region, which is nonconvex. We solve this challenging problem for two different cases of the channel state information (CSI): 1) when the CSI is known only at the receiver (the CSIR case) and 2) when the CSI is known at both the transmitter and the receiver (the CSI case). For these two cases, we develop the corresponding optimal dynamic power-splitting schemes. To address the complexity issue, we also propose the suboptimal schemes with low complexities. Comparing the proposed schemes to the existing schemes, we provide various useful insights into the dynamic power splitting with nonlinear EH. Furthermore, we extend the analysis to the scenarios of the partial CSI at the transmitter and the harvested energy maximization. The numerical results demonstrate that the proposed schemes significantly outperform the existing schemes and the proposed suboptimal scheme works very close to the optimal scheme at a much lower complexity. | Kang, Jae-Mo; Chun, Chang-Jae; Kim, Il-Min; Kim, Dong In | Kyungpook Natl Univ, Dept Artificial Intelligence, Daegu 41566, South Korea; Korea Electrotechnol Res Inst, Ind Applicat Res Div, Chang Won 51543, South Korea; Queens Univ, Dept Elect & Comp Engn, Kingston, ON K7L 3N6, Canada; Sungkyunkwan Univ, Dept Elect & Comp Engn, Suwon 16419, South Korea | ; Chun, Changjae/AAF-2393-2019; Kim, Dong/ADC-1101-2022 | 56024930400; 55694574800; 36040390300; 35476060100 | jmkang@knu.ac.kr;cjchun84@gmail.com;ilmin.kim@queensu.ca;dikim@skku.ac.kr; | IEEE INTERNET OF THINGS JOURNAL | IEEE INTERNET THINGS | 2327-4662 | 7 | 6 | SCIE | COMPUTER SCIENCE, INFORMATION SYSTEMS;ENGINEERING, ELECTRICAL & ELECTRONIC;TELECOMMUNICATIONS | 2020 | 9.471 | 3.4 | 0.66 | 2025-06-25 | 15 | 14 | Fading channels; Integrated circuit modeling; Radio frequency; Receivers; Transmitters; Energy harvesting; Complexity theory; Dynamic power splitting; nonlinear energy harvesting (EH); power allocation; rate-energy (R-E) tradeoff; simultaneous wireless information and power transfer (SWIPT) | WAVE-FORM DESIGN; WIRELESS INFORMATION; RESOURCE-ALLOCATION; NETWORKS | Dynamic power splitting; Nonlinear energy harvesting (EH); Power allocation; Rate-energy (R-E) tradeoff; Simultaneous wireless information and power transfer (SWIPT) | E region; Energy harvesting; Energy transfer; Fading channels; Internet of things; Transmitters; Wireless power transfer; Complexity issues; Energy maximization; Information and power transfers; Internet of thing (IOT); Lower complexity; Numerical results; Optimal dynamics; Sub-optimal schemes; Channel state information | English | 2020 | 2020-06 | 10.1109/jiot.2020.2980328 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
○ | ○ | Article | Exploring Deep Learning Models for Overhead View Multiple Object Detection | The Internet of Things (IoT), with smart sensors, collects and generates big data streams for a wide range of applications. One of the important applications in this regard is video analytics which includes object detection. It has been considered as an important research area particularly after the development of deep neural networks. We demonstrate the applications, effectiveness, and efficiency of the convolutional neural network algorithms, i.e., Faster-RCNN and Mask-RCNN, to facilitate video analytics in the IoT domain, for overhead view multiple object detection and segmentation. We used the Faster-RCNN and Mask-RCNN models trained on the frontal view data set. To evaluate the performance of both algorithms, we used a newly recorded overhead view data set containing images of different objects having variation in field of view, background, illumination condition, poses, scales, sizes, angles, height, aspect ratio, and camera resolutions. Although the overhead view appearance of an object is significantly different as compared to a frontal view, even then the experimental results show the potential of the deep learning models by achieving the promising results. For Faster-RCNN, we achieved a true-positive rate (TPR) of 94% with a false-positive rate (FPR) of 0.4% for the overhead view images of persons, while for other objects the maximum obtained TPR is 92%. The Mask-RCNN model produced TPR of 93% with FPR of 0.5% for person images and maximum TPR of 92% for other objects. Furthermore, the detailed discussion is made on output results which highlights the challenges and possible future directions. | Ahmed, Imran; Din, Sadia; Jeon, Gwanggil; Piccialli, Francesco | Inst Management Sci, Ctr Excellence Informat Technol, Peshawar 25000, Pakistan; Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu 41566, South Korea; Xidian Univ, Sch Elect Engn, Xian 710071, Peoples R China; Incheon Natl Univ, Dept Embedded Syst Engn, Incheon 22012, South Korea; Univ Naples Federico II, Dept Elect Engn & Informat Technol, Naples, Italy | ; Piccialli, Francesco/ABC-2457-2020; Din, Sadia/ADU-4679-2022; Ahmed, Imran/HDL-7255-2022 | 58776130700; 57188997144; 15022497800; 42762051900 | imran.ahmed@imsciences.edu.pk;saadia.deen@gmail.com;ggjeon@gmail.com; | IEEE INTERNET OF THINGS JOURNAL | IEEE INTERNET THINGS | 2327-4662 | 7 | 7 | SCIE | COMPUTER SCIENCE, INFORMATION SYSTEMS;ENGINEERING, ELECTRICAL & ELECTRONIC;TELECOMMUNICATIONS | 2020 | 9.471 | 3.4 | 3.81 | 2025-06-25 | 68 | 66 | Object detection; Proposals; Deep learning; Feature extraction; Internet of Things; Convolution; Neural networks; Deep neural networks; Faster-RCNN; Mask-RCNN; object detection; overhead view | PERSON DETECTOR | Deep neural networks; Faster-RCNN; Mask-RCNN; object detection; overhead view | Aspect ratio; Convolutional neural networks; Data streams; Deep neural networks; Internet of things; Learning systems; Object detection; Object recognition; Camera resolutions; False positive rates; Illumination conditions; Internet of thing (IOT); Multiple-object detections; Possible futures; True positive rates; Video analytics; Deep learning | English | 2020 | 2020-07 | 10.1109/jiot.2019.2951365 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||

○ | ○ | Article | Metabolic engineering of Escherichia coli for production of non-natural acetins from glycerol | Mono-, di- and triacetin are three glycerol esters which are usually synthesized via costly and environmentally unfriendly chemical synthesis methods. Here, Escherichia coli is metabolically engineered for the production of mono-, di- and triacetin using glycerol as a substrate. First, a novel biosynthetic route of mono- and diacetin is established by overexpression of a native enzyme, maltose O-acetyltransferase (MAA). Next, the biosynthetic pathway is extended to produce a mixture of mono-, di- and triacetin by overexpression of chloramphenicol-O-acetyltransferase (CAT). By successive strategies, including heterologous gene expression, metabolic engineering, and culture optimization, a recombinant E. coli is enabled to produce more than 27 g L-1 of a mixture of mono-, di- and triacetin in shake flask cultures, which is a >650-fold increase over the initial production of 0.04 g L-1. In vitro studies confirm the acetylation of glycerol to mono- and diacetin by MAA, and the additional acetylation to triacetin by CAT. When crude glycerol is used as a substrate, the engineered strain produced a total of 25.9 g L-1 of the acetin mixture, about the same as that achieved from pure glycerol. To our knowledge, this is the first successful report of microbial production of the artificial chemicals, acetins. | Zada, Bakht; Joo, Seongjoon; Wang, Chonglong; Tseten, Tenzin; Jeong, Seong-Hee; Seo, Hogyun; Sohn, Jung-Hoon; Kim, Kyung-Jin; Kim, Seon-Won | Gyeongsang Natl Univ, Div Appl Life Sci BK21 Plus, PMBBRC, Jinju 52828, South Korea; Kyungpook Natl Univ, Sch Life Sci, KNU Creat BioRes Grp, Daegu 41566, South Korea; Soochow Univ, Sch Biol & Basic Med Sci, Suzhou, Peoples R China; Korea Res Inst Biosci & Biotechnol, Synthet Biol & Bioengn Res Ctr, Daejeon 34141, South Korea | Wang, Chonglong/D-9643-2013; Kim, Kyung-Jin/MVY-3405-2025; Wang, Chonglong/CAI-2627-2022 | 57210613253; 57190377309; 36970821000; 56418662200; 57203142225; 57189697998; 16026283200; 55510867400; 26633919100 | bakhtqau@gmail.com;wntjdwnswkd@naver.com;clwang@suda.edu.cn;sohn4090@kribb.re.kr;kkim@knu.ac.kr;swkim@gnu.ac.kr; | GREEN CHEMISTRY | GREEN CHEM | 1463-9262 | 1463-9270 | 22 | 22 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY | 2020 | 10.182 | 3.4 | 0.23 | 2025-06-25 | 5 | 6 | CLOSTRIDIUM-ACETOBUTYLICUM; MALTOSE TRANSACETYLASE; CITRIC-ACID; ETHANOL; ACETYLTRANSFERASE; CHLORAMPHENICOL; 1,3-PROPANEDIOL; ACETYLATION; REPLACEMENT; SOLVENT | Acetylation; Biosynthesis; Escherichia coli; Gene expression; Glycerol; Metabolism; Mixtures; Substrates; Acetyl transferase; Biosynthetic pathway; Culture optimizations; Engineered strains; Heterologous gene expressions; Microbial production; Recombinant E. coli; Shake-flask cultures; Metabolic engineering | English | 2020 | 2020-11-21 | 10.1039/d0gc02395g | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||

○ | ○ | Article | Novel Z-scheme Ag3PO4/Fe3O4-activated biochar photocatalyst with enhanced visible-light catalytic performance toward degradation of bisphenol A | A novel solid-state Z-scheme heterostructure, Ag3PO4/Fe3O4 co-doped bamboo-derived activated biochar (Ag-Fe@BAB), was synthesized as an efficient photocatalyst via a co-precipitation method. Ag-Fe@BAB was used as a magnetically recoverable photocatalyst to generate free radical species with peroxydisulfate (PDS) activation under visible-LED-light illumination. The successful synthesis of Ag-Fe@BAB was confirmed by various characterization techniques. Bisphenol A (BPA) was used as a model pollutant to evaluate the photo catalytic activities of the Vis/Ag-Fe@BAB/PDS system. To confirm the photocatalytic performance of the Vis/Ag-Fe@BAB/PDS system, the effects of significant operating parameters such as the contact time, concentration of oxidant, photocatalyst dosage, and solution pH on the degradation of BPA were evaluated. We confirmed that 95.6% BPA was degraded within 60 min in the Vis/Ag-Fe@BAB/PDS system under 1.0 g/L photocatalyst, pH 6.5, and 0.5 mM PDS. The degradation mechanism of BPA in the Vis/Ag-Fe@BAB/PDS system was mainly attributed to O-center dot(2)- Furthermore, the radical species produced in the Vis/Ag-Fe@BAB/PDS system were identified by electron spin resonance. Finally, we demonstrated the recyclability of the Ag-Fe@BAB photocatalyst through its excellent magnetic property. owing to its photocatalytic performances in the presence of p-benzoquinone as a scavenger. | Talukdar, Kristy; Jun, Byung-Moon; Yoon, Yeomin; Kim, Yejin; Fayyaz, Aqsa; Park, Chang Min | Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea; Univ South Carolina, Dept Civil & Environm Engn, 300 Main St, Columbia, SC 29208 USA | ; Park, Chang Min/CAA-8506-2022; Jun, Byung-Moon/Y-2134-2019; Yoon, Yeomin/KDP-2253-2024 | 57217156139; 55326699900; 7402126688; 59052467200; 57217157699; 57209588953 | talukdarkristy@knu.ac.kr;junb@mailbox.sc.edu;yoony@cec.sc.edu;rysa12@knu.ac.kr;2019224736@knu.ac.kr;cmpark@knu.ac.kr; | JOURNAL OF HAZARDOUS MATERIALS | J HAZARD MATER | 0304-3894 | 1873-3336 | 398 | SCIE | ENGINEERING, ENVIRONMENTAL;ENVIRONMENTAL SCIENCES | 2020 | 10.588 | 3.5 | 4.55 | 2025-06-25 | 132 | 135 | Photocatalysis; Z-scheme; Persulfate activation; Bisphenol A | GRAPHENE OXIDE; PERSULFATE; MECHANISM; COMPOSITE; CARBON; PHOTODEGRADATION; SULFAMETHOXAZOLE; CARBAMAZEPINE; ACTIVATION; EFFICIENCY | Bisphenol A; Persulfate activation; Photocatalysis; Z-scheme | Degradation; Free radicals; Light; Magnetic moments; Phenols; Precipitation (chemical); 1,4 benzoquinone; 4,4' isopropylidenediphenol; biochar; charcoal; free radical; iron nanoparticle; magnetite; oxidizing agent; silver nanoparticle; unclassified drug; Catalytic performance; Characterization techniques; Coprecipitation method; Degradation mechanism; Free radical species; Operating parameters; Peroxydisulfate; Photocatalytic performance; biochar; catalysis; catalyst; degradation; dye; free radical; iron oxide; performance assessment; photodegradation; visible spectrum; Article; bamboo; chemical analysis; clinical evaluation; concentration process; contact time; degradation kinetics; electron spin resonance; environmental parameters; illumination; irradiation; magnetism; pH; photocatalysis; precipitation; reaction analysis; solid state; synthesis; ultraviolet radiation; water pollutant; water treatment; Photocatalytic activity | English | 2020 | 2020-11-05 | 10.1016/j.jhazmat.2020.123025 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
○ | ○ | Article | Photocatalytic degradation of methylene blue with P25/graphene/polyacrylamide hydrogels: Optimization using response surface methodology | An environment-friendly hydrogel was synthesized by entrapping Degussa P25 on the surface of a reduced graphene oxide (rGO)-polyacrylamide (PAM) matrix.The PAM content of the P25-rGO-PAM (PGP) hydrogel considerably influenced the adsorption and photocatalytic degradation of methylene blue (MB), and the optimal PAM content was 10% (w/v). Furthermore, rGO not only enhanced the adsorption capacity of the hydrogel by increasing the surface area but also increased the photodegradation efficiency synergistically by separating electron-hole pairs. The reaction kinetic constant for MB degradation by the hydrogel was 0.0276 min(-1), which was three and five times the reaction kinetic constants of P25-PAM and rGO-PAM hydrogels, respectively. The synthesized PGP showed high stability and its MB degradation efficiency was considerably high up to five consecutive cycles under UV-irradiation. The eco-friendly nature of the hydrogel was evaluated on the basis of bacterial inactivation, and the treated water was found to be safe for use. Three key operating parameters (initial MB concentration, temperature, and pH) were optimized for maximizing MB removal using a response surface methodology. The complete MB removal efficiency was obtained for the optimal conditions of pH 9.4, a temperature of 31.2 degrees C, and an initial MB concentration of 5.2 mg/L. | Moztahida, Mokrema; Lee, Dae Sung | Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea | 57202904382; 55568524907 | daesung@knu.ac.kr; | JOURNAL OF HAZARDOUS MATERIALS | J HAZARD MATER | 0304-3894 | 1873-3336 | 400 | SCIE | ENGINEERING, ENVIRONMENTAL;ENVIRONMENTAL SCIENCES | 2020 | 10.588 | 3.5 | 4.4 | 2025-06-25 | 122 | 124 | Hydrogel; Methylene blue; Photodegradation; Toxicity; Response surface methodology | REDUCED GRAPHENE OXIDE; ORGANIC CONTAMINANTS; AQUEOUS-SOLUTIONS; TIO2; REMOVAL; WATER; POLYACRYLAMIDE; ADSORPTION; DYES; NANOPARTICLES | Hydrogel; Methylene blue; Photodegradation; Response surface methodology; Toxicity | Bacteria (microorganisms); Aromatic compounds; Degradation; Efficiency; Graphene; Hydrogels; Irradiation; Rate constants; Reduced Graphene Oxide; Surface properties; Water treatment; graphene oxide; hydrogel; hydroxyl radical; methylene blue; nanoparticle; polyacrylamide; Adsorption capacities; Bacterial inactivation; Degradation efficiency; Environment friendly; Photo catalytic degradation; Photodegradation efficiency; Reduced graphene oxides (RGO); Response surface methodology; adsorption; degradation; dye; gel; optimization; photodegradation; photolysis; reaction kinetics; response surface methodology; adsorption; aqueous solution; Article; controlled study; molecular stability; molecular weight; pH; photocatalysis; photodegradation; pollution; polymerization; pore volume; productivity; response surface method; surface area; temperature; ultraviolet irradiation; waste component removal; waste water management; zeta potential; Photodegradation | English | 2020 | 2020-12-05 | 10.1016/j.jhazmat.2020.123314 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
○ | ○ | Article | Polyaniline-derived carbons: Remarkable adsorbents to remove atrazine and diuron herbicides from water | The contamination of water resources by hazardous organic compounds is becoming severe worldwide. In this study, the adsorptive removal of atrazine (ATZ) and diuron (DUR), two widely used herbicides, from water by polyaniline-derived carbons (PDCs) was investigated for the first time, under various conditions. A selected PDC, fabricated at optimum conditions, i.e., by pyrolysis at 800 degrees C (and labeled PDC(800)), showed remarkable adsorptivity for both herbicides, that is, 7.7 and 11.3 times the maximum adsorption capacity (Q(o)) for ATZ and DUR, respectively, compared to activated carbon (AC). Or, the Q(o) values of PDC(800) for ATZ and DUR were 943 and 884 mg/g, respectively; however, the Q(o) values of AC were only 123 and 78.0 mg/g, respectively. Moreover, the optimum adsorbent PDC(800) had 4.5 and 3.1 times Q(o) that of the best adsorbent, that showed the highest performances, so far, for ATZ and DUR, respectively. Plausible adsorption mechanisms were suggested based on the porosity and the adsorption in a wide pH range. The new adsorbent was reusable via simple solvent washing. Based on its remarkable adsorption performance and facile reusability, PDC(800) can be considered a promising adsorbent to remove herbicides such as ATZ and DUR from contaminated water. | Park, Jong Min; Jhung, Sung Hwa | Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea; Kyungpook Natl Univ, Green Nano Mat Res Ctr, Daegu 41566, South Korea | ; Jhung, Sung/AAO-6683-2021 | 57193995796; 6701659467 | sung@knu.ac.kr; | JOURNAL OF HAZARDOUS MATERIALS | J HAZARD MATER | 0304-3894 | 1873-3336 | 396 | SCIE | ENGINEERING, ENVIRONMENTAL;ENVIRONMENTAL SCIENCES | 2020 | 10.588 | 3.5 | 0.7 | 2025-06-25 | 23 | 22 | Adsorption; Herbicide; Polyaniline-derived carbon; Water purification | METAL-ORGANIC FRAMEWORKS; DOPED POROUS CARBONS; PERSONAL CARE PRODUCTS; ADSORPTIVE REMOVAL; HAZARDOUS ORGANICS; WASTE-WATER; PESTICIDES; KINETICS; ACID; THERMODYNAMICS | Adsorption; Herbicide; Polyaniline-derived carbon; Water purification | Activated carbon; Adsorption; Reusability; Urea; Water pollution; Water resources; Weed control; activated carbon; adsorbent; atrazine; diuron; polyaniline derived carbon; unclassified drug; water; Adsorption capacities; Adsorption mechanism; Adsorption performance; Adsorptive removal; Contaminated water; Derived carbons; Hazardous organic compounds; Optimum conditions; activated carbon; adsorption; atrazine; pollutant removal; polymer; temperature effect; water treatment; adsorption; Article; comparative study; controlled study; energy dispersive X ray spectroscopy; field emission scanning electron microscopy; Fourier transform infrared spectroscopy; pH; porosity; pyrolysis; synthesis; temperature; waste component removal; waste water management; waste water recycling; water contamination; X ray photoemission spectroscopy; Herbicides | English | 2020 | 2020-09-05 | 10.1016/j.jhazmat.2020.122624 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
○ | ○ | Article | Slow-release persulfate candle-assisted electrochemical oxidation of 2-methylnaphthalene: Effects of chloride, sulfate, and bicarbonate | Slow-release persulfate candle (PSC)-assisted electrochemical oxidation (ECO) of 2-methylnaphthalene (2-MNA) in an undivided cell using graphite-sheet electrodes was investigated using Fe(II) as an activator. The effects of anions (Cl-, SO42-, and HCO3-) were investigated. In the PSC/ECO/Fe(II), the highest pseudo-first-order rate constant (kobs) and % removal was achieved by adding Cl- (2.723 h(-1), 75.2%) followed by SO42- (1.753 h(-1), 63.9 %) and HCO3- (0.047 h(-1), 3.3%). Addition of Cl- played a critical role in improving the removal efficiency by inducing center dot OH and SO4 center dot- oxidations, while SO42- reduced the efficiency due to non-radical oxidation, as elucidated by electron spin resonance (ESR). Furthermore, in the PSC/ECO/Fe(II) + Cl-, dominant radical was changed from SO4 center dot- to center dot OH. Scavenger experiments also confirmed that Cl- and SO42- ions are controlling the oxidation reaction. Two chlorinated byproducts analyzed by LC-MS were identified in PSC/ECO/Fe(II) + Cl- system. | Septian, Ardie; Shin, Won Sik | Kyungpook Natl Univ, Sch Architecture Civil Environm & Energy Engn, Daegu 41566, South Korea | ; Septian, Ardie/HGB-8696-2022 | 57201503612; 23019870800 | wshin@knu.ac.kr; | JOURNAL OF HAZARDOUS MATERIALS | J HAZARD MATER | 0304-3894 | 1873-3336 | 400 | SCIE | ENGINEERING, ENVIRONMENTAL;ENVIRONMENTAL SCIENCES | 2020 | 10.588 | 3.5 | 0.6 | 2025-06-25 | 22 | 20 | Electrochemical oxidation; 2-methylnaphthalene; PS candle; Radical; Slow release | POLYCYCLIC AROMATIC-HYDROCARBONS; TERT-BUTYL ETHER; WASTE-WATER; ORGANIC CONTAMINANTS; HYDROXYL RADICALS; DEGRADATION; PAHS; GROUNDWATER; ACTIVATION; EXPOSURE | 2-methylnaphthalene; Electrochemical oxidation; PS candle; Radical; Slow release | Kobus; Chlorine compounds; Efficiency; Electrochemical oxidation; Electron spin resonance spectroscopy; Graphite electrodes; Magnetic moments; Rate constants; Sulfur compounds; 2 methylnaphthalene; anion; bicarbonate; chloride; electrolyte; persulfate; sulfate; unclassified drug; 2-methylnaphthalene; Chlorinated byproducts; Effects of anions; Electrochemical oxidation (ECO); Oxidation reactions; Pseudo first order rate constants; Radical oxidation; Removal efficiencies; anion; bicarbonate; electrochemical method; electrode; energy efficiency; graphite; oxidation; Article; electric current; electron spin resonance; oxidation; Iron compounds | English | 2020 | 2020-12-05 | 10.1016/j.jhazmat.2020.123196 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
