Studies on Degradation of Diquat Pesticide in Aqueous Solutions Using Electrochemical Method


The C/PbO2 electrode assisted electrochemical removal of diquat dibromide herbicides solutions has been the subject of the present investigation under several operating conditions. The optimum conditions of the treatment process are: current density of 150 mA/cm2, pH 2.2, NaCl concentration 2 g/L, temperature of 10?C and initial diquat concentration of 50 mg/L. The time of electrolysis is 60 min for degradation rate of diquat and chemical oxygen demand (COD) removal is 210 min. The results were obtained by UV-Vis spectrophotometer and the present designed electrode was coincident.
