摘　　要：自制了Ti/Sb2O5+SnO2/α-PbO2/Ce+β-PbO2和氧电极,并用XRD、SEM对电极进行表征和性能测试。利用该电极体系降解活性艳红X-3B,研究了电流密度、Fe2+投加量、初始pH、曝气量等因素对活性艳红X-3B降解效果的影响。结果表明,该电极体系实现了阳极和阴极的"协同催化氧化",对活性艳红X-3B具有很好的降解效果。电解50min时,脱色率接近100%,该反应过程遵循1级动力学模式。Ti/Sb2O5＋SnO2/α-PbO2/Ce＋β-PbO2 and oxygen electrode were prepared and characterized by XRD, SEM. Subsequently, The electrode system was applied to treat reactive brilliant red X-3 B, and warious influence factors such as current density, dose of Fe^2＋, initial pH and sparged oxygen were investigated. The results indicated that the electrode system was well in 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 kinetic s equation.
