摘　　要：采用静电自组装法将杂多酸K_(8)[Cd(H_(2)O)CuW_(11)O_(39)]和中间体PANI/ZnS成功复合成三元复合催化剂K_(8)[Cd(H_(2)O)CuW_(11)O_(39)]/PANI/ZnS,并利用IR、UV、XRD、N_(2)吸附-脱附、SEM、XPS等手段进行表征,研究该催化剂光催化降解龙胆紫染料的能力。确定反应的优化条件为:龙胆紫溶液初始p H 2,初始质量浓度5 mg/L,催化剂用量10 mg,此时龙胆紫溶液脱色率可达92.15%。重复降解实验证明,K_(8)[Cd(H_(2)O)CuW_(11)O_(39)]/PANI/ZnS经过3次降解后仍具有良好的催化活性,龙胆紫溶液脱色率达到70.14%。The ternary composite catalyst K_(8)[Cd(H_(2)O)CuW_(11)O_(39)]/PANI/ZnS was successfully synthesized by heteropoly acid K_(8)[Cd(H_(2)O)CuW_(11)O_(39)]and intermediates PANI/Zn S through electrostatic self-assembly method.The catalyst was characterized by IR,UV,XRD,N;adsorption-desorption,SEM and XPS.The photocatalytic degradation of gentian violet dye was studied.The optimum conditions were determined as follows:the initial pH of gentian violet solution 2,the initial mass concentration 5 mg/L,the amount of catalyst 10 mg,and the decolorization rate of gentian violet solution could reach 92.15%.Repeated degradation experiments showed that K_(8)[Cd(H_(2)O)CuW_(11)O_(39)]/PANI/ZnS still had good catalytic activity after three times of degradation,and the decolorization rate of gentian violet solution reached 70.14%.
