摘　　要：Methodology for the electrochemical decomposition of imazethapyr using Ti/SnO2-Sb2O5/PbO2 anode in Na2SO4 medium is suggested in this paper. The electrolysis reaction conditions were optimized. The process of electrochemical decomposition was monitored by ultra-violet spectrophotometry and CODCr method. The electrochemical decomposition mechanism of imazethapyr was studied primarily by UV-VIS spectrophotometry. The effectiveness of the electrochemical pretreatment was proved by the comparative aerobic biological treatment test based on the activated sludge process.Methodology for the electrochemical decomposition of imazethapyr using Ti/SnO2-Sb2O5/PbO2 anode in Na2SO4 medium is suggested in this paper.
