摘要
以硫化镉为光催化剂,钨灯模拟可见光,研究了硫化镉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、污染物的初始浓度、反应体系的pH值等对光催化过程的影响。结果表明,以钨灯为光源下,硫化镉能较好对亚甲基蓝进行降解。
Process of photocatalytic decomposition of methylene blue on cadmium sulphide was studied using cadmium sulphide nanoparticles as photocatalyst and tungsten as simulated visible light. The impact of illumination time, amount of photocatalyst, initial concentration of pollutants and consistency of MB, pH on the photocatalytic activity was investigated. Results showed that cadmium sulphide is a very efficient photocatalyst.
