| Abstract: | 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. |
