| Abstract: | Oxidation of Congo Red on PbO2 electrode prepared by electrodeposition on stainless steel was studied by cyclic voltammetry and constant voltage electrolysis.Effects of potential,initial concentration of Congo Red and temperature on removal rate were discussed,the degradation kinetics of Congo Red was also investigated.It was found that the potential had a positive effect on removing rate,and the removal rate of Congo Red decreased with increasing initial concentration and temperature.The degradation of Congo Red followed the first-order kinetics. |
