摘　　要：以结晶紫溶液为模拟染料废水,Fe/HAP为催化剂,对该多相类Fenton体系的催化活性进行了研究,探讨了H_2O_2投加量、催化剂投加量、pH值、反应温度、溶液初始浓度对结晶紫去除效果的影响。结果表明在H_2O_2用量为1 mL,催化剂投加量为1 g/L,pH值为9,降解温度为30℃,浓度为40 mg/L的结晶紫溶液脱色率在96%以上。The catalytic efficiency of Fe / HAP which is used to promote heterogeneous Fenton-like reaction was examined by employing crystal violet as a model compound. The influencing factors such as the dosage of hydrogen peroxide and Fe / HAP,reaction temperature,pH value and initial dye concentration were also discussed. When the dosage of H_2O_2 and Fe / HAP were 1 mL and 1 g / L,respectively,and pH value was 9,the removal rate of Crystal Violet whose initial concentration was 40 mg / L was over 96% at
