摘要

The wastewater with HMX and RDX was treated by photodegradation process in the presence of cadmium sulfide doped with copper as photocatalyst under UV and Vis irradiations. The influence on the degration of Cu% as dopant in CdS/Cu nanoparticles， pH of solution， dosage of photocatalyst and concentration of explosives were studied. The XRD patterns and UV-Vis spectra were used to characterize the nanoparticle. Results show that the degradation efficiency for HMX and RDX wastewater reaches 85% -88% in the presence of Cd0.95Cu0.05S under 180 min UV irradiation. The dosage of 160.0 mg · L-1 of photocatalyst and the pH of 7 are the optimum. A gradual decrease in degradation at the fi r st two cycles is seen.
