Degradation of phenol by synergistic chlorine-enhanced photo-assisted electrochemical oxidation

State of the Art of UV/Chlorine Advanced Oxidation Processes: Their Mechanism, Byproducts Formation, Process Variation, and Applications

“…Among various toxicity tests the luminescence inhibition test with Vibrio fischeri is most popular in UV/chlorine AOPs. The V. fischeri toxicity was decreased by UV/chlorine treatment in three researches [72][73][74]. However, an increase in toxicity was reported in the rest of three [21,37,40].…”

“…One of reasons of the discrepancy may be treatment time in UV/chlorine AOPs. In researches with reduction in V. fischeri toxicity, the treatment time was not shorter than 1 h [72][73][74], whereas the treatment time was set at 13 min or shorter in the research with the increase in the toxicity [21,37,40]. In UV/chlorine AOPs chlorinated organic byproducts are temporally produced.…”

Recent developments of electro-oxidation in water treatment — A review

“…The combination of a photochemical and electrochemical process has given promising results in wastewater treatment in recent years [77][78]. In municipal wastewater treatment, EO was shown to be less effective for the structural degradation of large molecules, but more effective for ring cleavage and the removal of aromatic functionality [78].…”

Fe3O4 embedded ZIF-8 nanocrystals with ultra-high adsorption capacity towards hydroquinone

“…Therefore, the efficient removal of phenol-derived pollutants from waste effluents is of great importance. So far, a variety of techniques, such as adsorption [3,4], ion exchange [5], membrane separation [6,7], biological degradation [8,9], chemical oxidation [10,11], electrochemical methods [12] and solvent extraction [13,14], have been developed to remove the phenol-derived pollutants. However, adsorption treatment is still the most attractive process for its high efficiency good selectivity, low cost and easy handling in adsorption and desorption of the contaminants [15].…”
