摘要
总结了有关硫化零价铁(特别是硫化纳米零价铁)去除水体污染物的最新研究和进展,对硫化零价铁技术发展历程及其制备方法进行了介绍。深入分析了硫化试剂类型、硫化改性方法和S/Fe摩尔比对硫化零价铁处理水体污染物的影响,并且详细归纳、阐述了硫化显著提高零价铁反应活性的机制。最后提出了将来需要关注的问题以及研究方向。
This paper summarizes the latest research and progress on the removal of water pollutants by vulcanized zero-valent iron(especially vulcanized nano zero-valent iron),and introduces the historical progress in vulcanized zero-valent iron and the relating preparation methods.The effects of vulcanization reagent type,vulcanization modification method and S/Fe molar ratio on the treatment of water pollutants by vulcanized zero-valent iron are analyzed in detail,and the mechanism how vulcanization can increase the reactivity of zero-valent iron is described and summarized.According to the current research status,combined with actual needs,the issues and research directions that need to be paid attention to in the future are raised.
