Abstract

I n thi s paper, CdS nanometer particles are successfully synthesized by hydro thermal method a nd its photo catalytic performance was evaluated via degradation Ciprofloxacin under visible light irradiation. The morphology, size and structure are characterized by sc anning electron microscopy, X ray diffraction spectroscopy, UV vis absorption spectrophotometer, respectively. The results show that CdS exhibit excellent photo catalytic performance for degradation Ciprofloxacin with a maximum removal rate of over 95% at 60 min under visible light irradiation due to its higher visible light absorption and comparatively low electron hole pair recombination. T he possible mechanism of the photo catalytic degradation processes is proposed..
