摘要
文章研究了Ti/SnO2-Sb2O5/PbO2在两室电解池中氧化降解苯甲酸的性能,主要考察了电流密度、初始pH值、初始苯甲酸浓度和支持电解质这四个参数对TOC去除效率的影响。实验表明在电流密度为30 mA/cm2,初始苯甲酸浓度为0.5 mmol/L,支持电解质(Na2SO4)为0.1 mol/L的条件下,经过6 h反应,TOC去除效率达到65%。初始pH值对TOC去除没有显著的影响。
Electrochemical performance of Ti/SnO2-Sb2O5/PbO2 electrodes in the oxidation of simulated wastewater containing benzoic acid using a two-compartment electrochemical system was investigated.Influence of operating variables on TOC removal efficiency was studied as a function of current density,initial pH,initial benzoic acid concentration and supporting electrolyte concentration.Under the conditions of a density current of 30 mA/cm^2,initial benzoic acid concentration of 0.5 mmol/L,supporting electrolyte concentration（Na2SO）4of 0.1 mol/L and after 6h reaction,TOC removal efficiency was up to 65%.And no significant effect of initial pH on TOC removal could be observed.
