摘　　要：纳米铁作为新型纳米材料在水处理中应用广泛,其中它在降解有机卤代物、有毒重金属、偶氮染料等方面成就突出。本文介绍了它在降解有机卤代物的方面的最新研究及总结。重点探究了它在降解TCE、对氯硝基苯及γ-HCH时还原脱卤的特性,提出了纳米铁在处理工业废水时pH值越低、量越大,降解效果越好的结论,对于降解废水中有机卤代物及降低处理化工污染成本有重要意义。Nanometer iron is widely used as a new kind of nanometer material in water treatment,especially in the degradation of organic halides,toxic heavy metals and azo dyes.This paper introduces the latest research and summarization on its degradation of organic halogenated compounds.The characteristics of reductive dehalogenation in the degradation of TCE,p-chloronitrobenzene and gamma-HCH were investigated emphatically.The conclusion that the lower pH value and the larger the amount of nano-iron in the treatment of industrial wastewater,the better the degradation effect was put forward.It is of great significance for the degradation of organic halogens in wastewater and the reduction of the cost of chemical pollution treatment.
