| 摘 要： | 以硅钨酸为光催化剂，研究了其对模拟染料废水甲基橙的光催化脱色降解影响.结果表明，酸度、催化剂投加量、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，10mg/L的甲基橙溶液在紫外灯辐照下，硅钨酸浓度0.4g/L，溶液酸度pH=1.其对甲基橙溶液光催化降解效果比磷钨酸差.

| Abstract: | The silicotungstic acid was used as the photocatalyst to degradation of the methyl orange solution. The effect of the solution pH, catalyst quantity and the initial concentration of the methyl orange on decolorizing efficiency of the solution were discussed in detail. The optimum calalytic condition is the concentration of methyl orange is 10mg/L, the pH of the solution is 1 and the concentration of the silicotungstic acid is 0.4g/L with ultraviolet radiation. The catalytic efficiency of which is not better than phosphtungstic acid. |
