On July 21, 2020, Zheng, Wenxiao; Zhu, Liuyi; Liang, Sheng; Ye, Jinshao; Yang, Xin; Lei, Zhenchao; Yan, Zhang; Li, Yongdong; Wei, Chaohai; Feng, Chunhua published an article.Formula: C8H10O2 The title of the article was Discovering the Importance of ClO• in a Coupled Electrochemical System for the Simultaneous Removal of Carbon and Nitrogen from Secondary Coking Wastewater Effluent. And the article contained the following:
inorganic pollutants in actual wastewater, e.g., halides and CO32-/HCO3-, may have neg. effects on electrochem. system performance due to their capability of quenching HO-. however, the authors determined the presence of Cl- and HCO3- in an electrochem. system was conducive to ClO- formation, which played an important role in promoting simultaneous removal of bio-refractory organics and N from secondary coking wastewater effluent. a 6-h operation of the coupled electrochem. system (undivided electrolytic cell with PbO2/Ti anode and Cu/Zn cathode) at a 37.5 mA/cm2 c.d. removed 87.8% of COD and 86.5% total N. ESR results suggested ClO- formation in the system and probe experiments confirmed the ClO- predominance, whose steady-state concentrations (8.08 x 10-13 M) were 16.4, 26.5, and 1609.5 times those of Cl2- (4.92 x 10-14 M), OH- (3.05 x 10-14 M), and Cl- (5.02 x 10-16 M), resp. the COD removal rate constant and the Faradaic efficiency of anodic oxidation obtained with Cl- and HCO3- was linearly proportional to the natural logarithm of the ClO- concentration; specific energy consumption was inversely correlated to it, demonstrating the crucial role of ClO- for pollutant removal. The experimental process involved the reaction of 1,4-Dimethoxybenzene(cas: 150-78-7).Formula: C8H10O2
