纳米零价铁在应用中存在的问题及提高反应活性的方法

纳米零价铁对多种污染物质均有较好的去除效果,在污染的水体、土壤及底泥中被广泛研究与应用。前人对纳米零价铁的制备、在污染治理各方面的应用、作用的机理等方面进行了较为详细的总结,针对纳米零价铁在应用中存在的问题虽有提及,但少有人集中进行整理。本文主要针对纳米零价铁在环境治理方面存在的问题进行论述并对提高其反应活性的常用方法进行了总结,以期为纳米零价铁实际应用领域的深入研究提供借鉴并拓展新的思路。

Questions of Nanoscale Zero-Valent Iron in the Application and the Ways to Improve Its Activity

Nanoscale zero-valent iron has been widely used and studied in contaminated water, soil and sediment because it has a good removal eficiency of multiple pollutants. A more detailed be summarized by previous on the preparation of nanoscale zero-valent iron, the application in pollution control, the mechanism of action and so on, but the problems of nanoscale zero-valent iron in application still not be organized. This paper is aimed at discussing the questions of zero-valent iron in environmental governance and summarizing the methods that how to improving its reactivity, so as to develop new ideas and provide references for depth research in this filed and the practical application of zero-valent iron.
