Electrochemical Ozidation of Imazethapyr on Ti/SnO2-Sb2O5/PbO2 Anode for Waste Water Treatment
The electrochemical oxidation of imazethapyr at Ti/SnO2-Sb2O5/PbO2 electrode was investigated by cyclic voltammetry, and the oxidation mechanism of imazethapyr was primarily studied in this paper. Sodium sulfate was used as the electrolyte of the substrate solutions. The experimental results of cyclic voltammetry show that acidic media is suitable for efficient electrochemical oxidation of imazethapyr. Some electrogenerated reagent was formed during the electrolysis, and the organic compounds in the solutions can be oxidized by the electro-generated reagent. The Ti/SnO2-Sb2O5/PbO2 electrode used as the anode, a stainless steel electrode used as the cathode, and the electrolysis experiment was carried out. The factors that influence the oxidation of imazethapyr were optimization, and the efficient electrolyte conditions were adopted in the electrolysis experiment. The electrolysis process was monitored by UV-visible spectrometry and the chemical oxygen demand (COD) was determined by the potassium dichromate method. The results of electrolysis experiment demonstrate the possibility of using Ti/SnO2-Sb2O5/PbO2 as an anode material for electrochemical treatment of imazethapyr containing waste water.
