Electrochemical Oxidation of 4-Chlorophenoxyacetic Acid on Ti/SnO2-Sb2O5/PbO2 Anode for Waste Water Treatment


Article Preview

The electrochemical oxidation of 4-chlorophenoxyacetic acid on Ti/SnO2-Sb2O5/PbO2 electrode was studied by cyclic voltammetry in this paper. The electrochemical behaviour of the electrode has been studied. The experimental results of cyclic voltammetry showed that acidic media was suitable for efficient electrochemical oxidation of 4-chlorophenoxyacetic acid. The Ti/SnO2-Sb2O5/PbO2 electrode was used as the anode and the electrolysis experiment was carried out under the optimized conditions. The electrolysis process was monitored by UV-visible spectrometry and high performance liquid chromatography (HPLC) and the chemical oxygen demand(COD) was determined by the potassium dichromate method. The mechanism of 4-chlorophenoxyacetic acid be oxided was studied primarily. The results of electrolysis experiment demonstrated the possibility that the electrode was used as an anode for electrochemical treatment of 4-chlorophenoxyacetic acid contained in the waste water.
