摘　　要：用静电自组装法将PANI/TiO_2与K_8[Ni(H_2O)MnW_(11)O_(39)]复合为K_8[Ni(H_2O)MnW_(11)O_(39)]/PANI/TiO_2复合材料。运用IR、UV、XRD、SEM-EDS、N2吸附-脱附等分析方法表征K_8[Ni(H_2O)MnW_(11)O_(39)]/PANI/TiO_2。以K_8[Ni(H_2O)MnW_(11)O_(39)]/PANI/TiO_2作为催化剂,在紫外灯下照射120 min,研究其对龙胆紫的光催化降解性能。结果表明:在紫外光照射下,龙胆紫pH为3、质量浓度为5 mg/L、催化剂用量为10 mg时,脱色率可达91.01%。PANI/TiO2 and K8[Ni(H2O)MnW11O39]were composited into K8[Ni(H2O)MnW11O39]/PANI/TiO2 com?posites by electrostatic self-assembly method.K8[Ni(H2O)MnW11O39]/PANI/TiO2 was characterized by IR,UV,XRD,SEM-EDS and N2 adsorption-desorption.K8[Ni(H2O)MnW11O39]/PANI/TiO2 was used as a catalyst.The photocatalytic degradation of gentian violet was studied by irradiating 120 min under UV lamp.The results showed that when under the condition of ultraviolet light,and the pH was 3,the concentration was 5 mg/L and the catalyst was 10 mg,the decolorization rate reached 91.01%.
