Electrochem. oxidation is an effective technique for treating persistent organic pollutants, which are hardly removed in conventional wastewater treatment plants. Sulfate and chloride salts commonly used and present in natural wastewater influence the electrochem. degradation process. In this study, the effect of electrolyte composition on the active sulfate species (SO4•- and S2O82-) formation, benzotriazole degradation-a model organic compound, and chlorinated byproducts distribution have been investigated while using a boron-doped diamond (BDD) anode. Different Na2SO4:NaNO3 and Na2SO4:NaCl ratios with constant conductivity of 10 mS/cm were used in the experiments and applied anode potential was kept constant at 4.3 V vs. Ag/AgCl. The electrogenerated SO4•- and S2O82- formation were faster in 10:1 and 2:1 Na2SO4:NaNO3 ratios than in the 1:0 ratio. The •OH-mediated SO4•- production has prevailed in 10:1 and 2:1 ratios. However, •OH-mediated SO4•- production has hindered the 1:0 ratio due to excess chemisorption of SO42- on the BDD anode. Similarly, the faster benzotriazole degradation, mineralization, and lowest energy consumption were achieved in the 10:1 Na2SO4:NaNO3 and Na2SO4:NaCl ratio. Besides, chlorinated organic byproduct concentration (AOX) was lower in the 10:1 Na2SO4:NaCl ratio but increased with the increasing chloride ratio in the electrolyte. LC-MS anal. shows that several chlorinated organic transformation products were produced in 0:1 to 2:1 ratio, which was not found in the 10:1 Na2SO4:NaCl ratio. A comparatively higher amount of ClO4– was formed in the 10:1 ratio than in 2:1 to 0:1 ratio. This ClO4– formation train evidence the effective •OH generation in a sulfate-enriched condition because the ClO4– formation is pos. correlated to •OH concentration Overall results show that sulfate-enriched electrolyte compositions are beneficial for electrochem. oxidation of biorecalcitrant organic pollutants. In the experiment, the researchers used many compounds, for example, 1H-1,2,3-Triazole-4,5-dicarboxylic acid (cas: 4546-95-6Product Details of 4546-95-6).
1H-1,2,3-Triazole-4,5-dicarboxylic acid (cas: 4546-95-6) belongs to triazole derivatives. The triazole ring is a relatively stable functional group, and the triazole bond can be used for a variety of applications, such as replacing the phosphate backbone of DNA. Triazole growth retardants such as uniconazole and paclobutrazol have been known to inhibit the biosynthesis of gibberellins by blocking kaurene oxidase, an P450 enzymeProduct Details of 4546-95-6
