负载型杂多酸对罗丹明B光催化降解的研究

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.

Photocatalytic Degradation of Rodanmine B Using Supported Heteropolyacid as Catalyst

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 30mg/L,the hour of catalyst is 2.5h,respectively.
