摘　　要：通过实验研究了零价铁(高碳铁屑)与TiO2对水中三氯甲烷去除率的共同作用规律。实验采用氯离子选择电极、气相色谱和扫描电镜分析方法,研究了相关材料及零价铁与TiO2比例,pH等条件对水中三氯甲烷去除率的影响规律:当铁屑与TiO2质量比为97:3、pH值为6.0时,水中三氯甲烷去除率最高;并采用相应的动力学模型进行了拟合分析以及对实验结果进行了分析和讨论。To study the function of zero-valence iron cooperated with TiO2, the experiment was done for the study of removal efficiency of chloroform in water with chloride ion selective electrode, gas chromatography and scanning electron microscope （SEM）. The rule of removal of chloroform in water with a proportion of zero-valence iron and TiO2 as well as pH was investigated. Results indicated that removal efficiency of chloroform was higher when proportion of zero valence iron / TiO2 was 97 ： 3 and pH was about 6.0. The fitting and analysis of dynamics model were discussed as well.
