摘　　要：通过水热法制备C/Fe-Bi2MoO6,样品的形貌及微观结构通过SEM、XPS、PL等手段进行表征。对光催化降解诺氟沙星(NOR)进行了研究,使用响应面方法(RSM)对光催化过程中的影响因素(pH、C/Fe-Bi2MoO6浓度、H2O2的浓度、诺氟沙星的浓度)进行了探讨和分析,构建响应面模型,并对反应条件进行了优化。此响应面模型能够较好地模拟实验结果。优化的最佳反应条件为:pH 6.98、209.36 mg/L H2O2、1.47 g/L C/Fe-Bi2MoO6、10.54 mg/L NOR,预测和实验最大诺氟沙星去除率分别为94.54%、92.58%,数值比较接近,说明此响应面模型能够有效描述光催化反应过程,优化光催化反应条件。C/Fe-Bi2MoO6 was prepared by hydrothermal method.SEM,XPS and PL were employed to characterize C/Fe-Bi2MoO6.Photocatalytic degradation of norfloxacin(NOR)by C/Fe-Bi2MoO6 was investigated in a reactor.Response surface methodology(RSM)was employed to construct RSM model and optimize the parameters(pH,H2O2 concentration,C/Fe-Bi2MoO6 concentration and NOR concentration).The quadratic model could be used to simulate the experimental results.The optimized conditions of photocatalytic degradation of NOR were as follows:pH 6.98,initial H2O2 concentration of 209.36 mg/L,C/Fe-Bi2MoO6 concentration of 1.47 g/L and NOR concentration of 10.54 mg/L.Under these conditions,the maximal NOR removal efficiency of 94.54%and 92.58%was achieved.Also,a polynomial expression modeling the reaction was obtained.The model fitted well with the experimental data,indicating the suitability of the model and the success of response surface methodology(RSM)in optimizing the conditions of photocatalysis.
