| 摘 要： | 研究了以磷钨酸为光催化剂,在自然光照条件下模拟染料废水甲基橙溶液的光催化脱色性能。实验结果表明,催化剂类型,光照条件,催化剂的投入量,甲基橙的初始浓度,光照时间以及光照强度是影响甲基橙溶液脱色率的重要因素。当磷钨酸的浓度为2.0 g/L,甲基橙的初始浓度为10 mg/L,自然光照时间为2.5 h时,甲基橙溶液的脱色率可达95.9%。

| Abstract: | In this paper,the phosphotungstic acid was used as the photocatalyst for the degradation of methyl orange solution under irradiated by sun.It has been shown that the catalyst dosage,the initial concentration of methyl orange,irradiation intensity and irradiation time under irradiated by sun were the important factors of decolorizing.The best reaction conditions were:the concentration of methyl orange was 10 mg/L,the dosage of phosphotungstic acid was 2.0 g/L,irradiation time was 2.5 h.The color removal could be up to 95.9%. |
