摘　　要：采用界面聚合法制备了复合催化剂PW_(11)Mn/PANI/SnO_2。应用FTIR、XRD、UV-Vis对合成的复合催化剂进行表征。将染料亚甲基蓝废水作为探针反应,评价复合催化剂PW_(11)Mn/PANI/SnO_2的光催化性能。实验结果表明:在亚甲基蓝溶液质量浓度为5mg/L、pH=10、催化剂PW_(11)Mn/PANI/SnO_2用量为50 mg/L的条件下,降解效果达到最佳,降解率可达94.19%。复合催化剂光降解亚甲基蓝与准一级动力学反应相吻合。The composite catalysts PW11Mn/PANI/SnO2 was prepared by interfacial polymerization method.The composite catalyst was characterized by FTIR,XRD,UV-Vis.The photocatalytic properties of the composite catalyst PW11Mn/PANI/SnO2 were determined by using methylene blue dye wastewater as a probe reaction.The experimental results showed that the optimal degradation process was as follows:the concentration of methylene blue 5 mg/L,pH=10,the catalyst PW11Mn/PANI/SnO2 dosage 50 mg/L.Under these conditions,the degradation effect was the best,and the degradation rate could reach 94.19%.Photocatalytic degradation of methylene blue accorded with pseudo first order reaction.
