Abstract:

Nanoscale zero-valent iron(nZVI) has broad application prospect in the field of water treatment due to its high specific surface area, high reactivity, and strong reduction performance. Four commonly used preparation methods of nZVI were described and compared, including liquid phase reduction, carbothermal reduction, green synthesis and mechanical ball milling. As nZVI had the problems of easy agglomeration and oxidation, four modification methods of nZVI such as load modification, bimetallic modification, vulcanization modification and surface modification were introduced. The mechanism of nZVI coupled with several common oxidants (O2, H2O2, O3, PS, etc.) to remove refractory wastewater was analyzed, and the research trend and development direction of nZVI in the field of water treatment were proposed.

Key words: nZVI, AOPs, organic pollutants, wastewater treatment

摘要:

纳米零价铁(nZVI)因其高比表面积、高反应活性和强还原性能,在水处理领域具有广阔的应用前景。阐述并比较了nZVI常用的4种制备方法,主要包括液相还原法、碳热还原法、绿色合成法及机械球磨法;针对nZVI容易团聚、氧化等问题,介绍了负载改性、双金属改性、硫化改性、表面改性等4种nZVI的改性方法;重点分析了nZVI耦合几种常见氧化剂(O2、H2O2、O3、PS等)去除难降解废水的机理,并对nZVI在水处理领域的研究趋势和发展方向提出了展望。
