摘　　要：本研究通过自制硫化镉与磷钼酸复合制备复合型催化剂对亚甲基蓝溶液进行光催化降解的研究.考察了催化剂的用量,亚甲基蓝的浓度,复合催化剂的配比对降解效率的影响.结果表明,催化剂的加入量为30.0 mg,磷钼酸的负载量为20%,亚甲基蓝的初始浓度为5 mg/L时的降解效果最好,平均降解率达到80.8%.The solution of methylene blue was degraded by mixing cadmium sulphide and phosphomolybdic acid catalyst. In additionl the influence of the dosage of catalyst, the concentration of methylene blue and the accounts of the composite catalyst on the degradation rate were investigated. The results showed that the average degradation ratio of methylene blue achieved 80.8%, when the dosage of catalyst was 30.0 mg, the content of phosphomolybdic acid was 20%, and the methylene blue initial concentration was 5 mg/L.
