摘　　要：介绍了金属还原法中铁系金属还原脱氯去除氯代有机物的机理及研究现状,概括总结了催化剂类型、两种金属的比率、氯代有机物种类、溶液pH、反应温度、污染物初始浓度等因素对脱氯效果的影响,针对目前存在的问题提出了未来发展的方向。The mechanism of chlorinated organic compound removal by iron-based metal reduction and its research situation are introduced. The factors affecting dechlorination are summarized, such as the types of catalysts, the ratio of two metals, the variety of chlorinated organic compounds, the pH of solution, the temperature of reaction and the initial concentration of pollutants. Aiming at the present problems, the direction for future development is also pointed out.
