| 摘 要： | 以CdIn2S4为光催化剂,钨灯模拟可见光,探讨其对活性染料亚甲基蓝的光催化降解过程.考察了光照时间、催化剂用量、亚甲基蓝的初始浓度、反应体系的pH值和温度以及光强对光催化过程的影响.结果表明：对于4mg/L的亚甲基蓝溶液,200W钨灯照射下,CdIn2S4的用量为0.04g/L,pH为3.0,1.5h内其降解率可达97.83%.温度对反应影响很小.

| Abstract: | Process of photocatalytic decomposition of the methylene blue on CdIn2S4 was studied using CdIn2S4 as photocatalyst and tungsten as simulated visible light.The impact of illumination time,amount of photocatalyst,initial concentration of pollutants and consistency of M B,pH and temperature of the reaction system,light intensity on the photocatalytic activity were investigated.Results showed that：under 200 W tungsten lamp irradiation,for 4 mg/L methylene blue solution,CdIn2S4dosage of 0.04 g/L,pH of 3.0,within 1.5 h,the methylene blue degradation was up to 97.83%.Temperature affected little on the reaction. |
