摘要
重金属是毒性大、难降解、易累积的环境污染物,纳米零价铁作为一种新型功能修复材料在去除水体和土壤中重金属方面有着广阔的应用前景.本文综述了纳米零价铁颗粒去除水中重金属的研究进展,包括纳米零价铁的常用制备方法及特性、去除效能、对不同重金属的去除机理以及发展前景和今后的研究方向,以期为该领域的深入研究提供借鉴并拓展新的思路.
Heavy metals are environmental pollutants which are highly toxic,difficult to be biodegraded and easy to enrich.Nanoscale zero-valent iron（nZVI）,as a new functional material in environment remediation,has been extensively investigated for removal of heavy metals in waters and soils.In this paper,advance in the removal of heavy metals by nZVI are reviewed.It includes synthesis and characteristics of the nanoparticles,and studies on the removal of heavy metals by nanoparticles such as capabilities,mechanism and perspectives of the technology.
