摘　　要：采用静电自组装法制备出三元复合材料K8[Fe（H2O）W（11）MnO（39）]/PANI/TiO2.采用IR,UV,XRD,SEM,XPS和N2吸附-脱附的表征手段对K8[Fe（H2O）W（11）MnO（39）]/PANI/TiO2进行表征,并以龙胆紫为模型,在紫外光照射下,考察了K8[Fe（H2O）W（11）MnO（39）]/PANI/TiO2对龙胆紫染料的光催化性能,确定光催化最佳条件：龙胆紫溶液浓度为5mg/L,pH=3,K8[Fe（H2O）W11MnO39]/PANI/TiO2的用量为10mg,脱色率可达92.93%.The ternary composite material of K8[Fe（H2O）W（11）MnO（39）]/PANI/TiO2 was synthesized by electrostatic self-assembly method,and was characterized by IR,UV,XRD,SEM,XPS and N2 adsorption-desorption.The photocatalytic activity of K8[Fe（H2O）W（11）MnO（39）]/PANI/TiO2 was studied for photocatalytic degradation of gentian violet as a model under the condition of UV irradiation and the optimum experimental reaction conditions of photocatalytic degradation were determined.The results indicated that the concentration of gentian violet solution was 5 mg/L,and the pH of gentian violet solution was 3,and the quantity of K8[Fe（H2O）W（11）MnO（39）]/PANI/TiO2 was 10 mg,and the decolorizing rate reached 92.93% under the best conditions.
