【 摘 要 】

The Fe(II) was loaded to the NaY to prepare FeY, and together with H2O2 constitutes a heterogeneous Fenton oxidation system. The photodegradation of ciprofloxacin by FeY-H2O2 heterogeneous Fenton was studied. The effects of H2O2 volume, FeY dosage, initial concentration of ciprofloxacin and pH on the degradation rate were studied by single factor experiment and orthogonal experiment. This study showed all the factors have an effect on the degradation rate of ciprofloxacin under the experimental conditions. The influential strengths are that: initial concentration of ciprofloxacin solution> the volume of 1:100 H2O2> the value of pH> the dosage of FeY. Under the condition of 20W UV lamp irradiation, the optimal degradation conditions is that the dosage of FeY is 0.2g, the initial concentration of ciprofloxacin is 30ug/mL, the volume of 1:100 H2O2 is 5mL, the value of pH is 4.0; and under this condition, the degradation rate of ciprofloxacin was up to 96.6%.
