摘　　要：采用自制的金属有机框架MIL-100(Fe)为光催化剂,以三氯卡班的降解率为响应因子,应用响应曲面法(RSM)对影响TCC降解率的主要因素进行了优化,建立了MIL-100(Fe)光催化降解TCC的二次多项式模型。获得最佳光降解条件为:TCC初始浓度为1.00 mg/L,H2O2浓度为0.10 mmol/L,pH值为13;三氯卡班光降解率的实验值与预测值具有良好的一致性,相对误差仅为1.06%。该研究为有效去除环境中的三氯卡班提供了基础数据和理论参考。In this paper,response surface method(RSM)was used to optimize the main factors affecting the degradation rate of triclocarban(TCC)with the self-made metal organic framework MIL-100(Fe)as a photocatalyst and the degradation rate of TCC as the response factor.A quadratic polynomial model of photocatalytic degradation of TCC was established with MIL-100(Fe).The best conditions of photodegradation were obtained:the initial concentration of TCC is 1.00 mg/L,the concentration of H2O2 is 0.10 mmol/L,and the pH value is 13.The test values of TCC photodegradation rate were in good agreement with the predicted values,and the relative error is 1.06%.This study provides the basic data and theoretical reference for effective removing TCC in the environment.
