摘　　要：对零价铁通过还原、微电解以及混凝吸附等作用,对诸如重金属、氯代有机物、硝基化合物等具有较高氧化电位污染物的去除进行了概述.并就零价铁技术去除污染物的机理、应用和在二元金属体系、纳米铁粉以及零价铁氧化体系等方面的研究进展进行了综述,同时对其在实施过程中面临的问题及发展方向进行了分析讨论.High re-ox potential compounds including heavy mental,halo-and nitro-compounds could be removed effectively by zero-valent iron（ZVI）through the mechanisms of reduction,micro-electrolysis,agglomeration and adsorption.The mechanism of these technologies and applications with the ZVI mediated oxidation system were reviewed,including the progress of the nanoscale iron and bimetals technology.Perspectives of this reseatch was also proposed tentatively,too.
