Reduction of chlorendic acid by zero-valent iron: Kinetics, products, and pathways

Electrochemically-based hybrid oxidative technologies for the treatment of micropollutants in drinking water

“…However, these reactions were not favored in the specific conditions used in this work. In literature, some studies have been demonstrated that at high pH (alkaline conditions), the efficiency of the process is worse, probably due to the passivation of the metal, weakening the degradation capability of ZVI [40,68]. For example, the metronidazole degradation with ZVI nanoparticles was of 97% at acidic to neutral initial pH, and only of 63% at alkaline initial pH [65].…”

“…Another important technology which can be combined with EO is ZVI-dehalogenation, which has demonstrated to be suitable for achieving a significant reduction of toxicity of wastes [39,40]. Zero valent iron (Fe 0 ) is a non-toxic, stable, cost-effective, and easy to obtain reactive material used as a heterogeneous catalyst, which can be recycled easily by magnetic forces [41,42].…”

Chlorine and Chlorinated Compounds Removal from Industrial Wastewater Discharges: A Review

“…Several techniques are used for treating chlorinated compounds from water. These include biodegradation Frascari et al, 2019;Khan et al, 2019;Papazi et al, 2019;Pathiraja et al, 2019;Nivorlis et al, 2019;Serbent et al, 2019), photochemical Ding et al, 2020;Li et al, 2019), adsorption (Dontriros et al, 2020;Du et al, 2020;Liang et al, 2020;Lo et al, 2020;Qian et al, 2020), chemical (Kim et al, 2020;Qian et al, 2020;, electrochemical (Du et al, 2020;McQuillan et al, 2020;Xu et al, 2020), photo-electrochemical membrane (Abdel-Shafy et al, 2017;Du et al, 2020;Vlotman et al, 2019;Wan et al, 2020), supercritical extraction (Zhang and Zhang, 2020), electron selectivity , neural network modeling , and catalytic (Nieto-Sandoval et al, 2019;Ruan et al, 2019;Zheng et al, 2020) method. Related literature on the electrolytic treatment methods application for different types of wastewater is shown in Table 4.…”

“…Zero-valent iron is used in chemical, photo-electrochemical and catalyst degradation of chlorinated compounds in the adsorption and degradation of chlorinated acid, where this rate decreases with increasing solution acidity (Mdlovu et al 2018;Kim et al, 2020;Qian et al, 2020;. Furthermore, Pd/Al2O3 catalyst was used to remove chlorinated micropollutants from the water with a reduction rate constants 0.32-1.56 L/g.min (Nieto-Sandoval et al 2019).…”

“…The removal efficiency of 4chlorophenol is 85.5%, and 48% is obtained with tungsten photoanode electrochemical . The biocharcoal-based electrode is also used to achieve 86.7% removal rates of Cl − from leather processing wastewater (Kim et al, 2020). Different carbon-supported iron was used for removal of chloramphenicol (Stryer 1988).…”
