摘　　要：以ZrO2-MoO3为载体制备了负载型硅钨杂多酸催化剂。以其为光催化剂,研究其对罗丹明B染料废水光催化降解的影响。实验结果表明:酸度、催化剂用量、溶液初始浓度是影响催化降解效果的重要因素。最佳催化条件为降解溶液酸度pH=2,催化剂最佳用量为0.5g/L,溶液的初始浓度为30mg/L,催化时间为2.5h。ZrO2-MoO3 supported H4SiW12O40 catalysts were prepared by the dip method. The supported heteropolyacid was as the photocatalyst to degradate the rodanmine B solution. The effect of the solution pH, catalyst quantity and the initial concentration of the rodanmine B on decolorizing efficiency of the solution were discussed in detail. The optimun catalytic condition is that the best amount of catalyst is 0. 5g/L, the pH of the solution is 2 and the concentration of rodanmine B is 30 mg/L,the hour of catalyst is 2. 5h,respectively.
