摘　　要：采用紫外灯作为光源,以TiO_2作为光催化剂降解马波沙星,应用响应曲面优化法优化了最佳pH值、催化剂的投加量及马波沙星污染物的初始浓度,提高了马波沙星的降解效果。实验结果表明,最佳的降解条件为pH=6.05,马波沙星的初始浓度为13.98 mg/L,Ti O_2为3.44 g/L,马波沙星最佳降解率为86.4%。The experimental is conducted by using UV lamp as a light source, TiO2 as photocatalyst for the degra- dation of Marbofloxacin, response surface methodology （RSM） was used to optimize the optimal pH value, the dosage of the catalyst and the initial concentration of the solution, so as to improve the efficiency of the degradation. By response surface methodology of the experimental analysis can acquired the best degradation conditions： pH=6.05, Marbofloxacin initial concentration=13.98 mg/L,TiO2=3.44 g/L, the best degradation rate of Marbofloxacin is 86.4% .
