摘要
介绍了零价铁( ZVI)及其复合材料的改性方式,包括了包覆、负载、双金属、硫化.探讨零价铁处理污水的机制,及其复合材料的改性和应用,分析在应用中存在的问题.通过多种改性方式制备的ZVI复合材料,不仅能够减缓ZVI的团聚、增大表面活性面积,还可以提高对目标污染物的处理效果与稳定性.最后提出了零价铁改性材料的稳定性以及与微生物协同解决水污染问题是未来研究的重点内容之一.
Abstract
Modifications of zero-valent iron (ZVI) and its composites are presented,including cladding,loading,bimetallic,and vulcanisation. The mechanism of zero-valent iron treatment of wastewater,and the modification and application of its composites are discussed,and the problems existing in the application are analysed. The ZVI composites prepared by various modification methods can not only slow down the agglomeration of ZVI,increase the surface active area,but also can improve the treatment effect and stability of target pollutants. The stability of ZVI-modified materials and the synergistic solution of water pollution problems with microorganisms are proposed to be one of the key contents of future research.
