| Abstract: | Ti/Sb_2O_5+SnO_2/α-PbO_2/Ce+β-PbO_2 and oxygen electrode were prepared and characterized by XRD, SEM Subsequently, The electrode system was applied to treat reactive brilliant red X-3B, and warious influence factors such as current density, dose ofFd*, initial pH and sparged oxygen were investigated. The results indicated that the electrode system was wellin treating reactive brilliant red X-3B for its simultaneously electrocatalytic effects of anode-cathode When the electrolytic time was 50 min, the decoloration rate was nearly 100% the reaction was in conformity with first-order kinetics equation . |
