纳米零价铁对污染物去除作用的机理研究

Study on Mechanism of Nano-Zero-Valent Iron Removal of Pollutants

摘要: 纳米零价铁具有较低的标准电动势、纳米尺寸，使得其表面的活性反应点位和活性吸附点位大大增加，还原降解和吸附污染物的速率远高于普通零价铁材料。本文综述了纳米零价铁颗粒去除有机污染、重金属的去除机理，旨在为该领域的深入研究提供借鉴和思路。

Abstract: Nano-zero-valent iron has a lower standard electromotive force and nano-size, which greatly in-creases the active reaction sites and active adsorption sites on the surface, and the rate of reduction and degradation of pollutants is much higher than that of ordinary zero-valent iron materials. This paper reviews the removal mechanism of organic zero pollution and heavy metals by nano-zero-valent iron particles. The purpose is to provide reference and ideas for in-depth research in this field.
