摘要: 由于纳米零价铁及铁基纳米复合粒子对大多数常见的环境污染物,如重金属离子、卤代有机物等均具有转化和降低毒性的作用,因此,在环境修复领域,它们已成为研究的热点之一。 纳米零价铁及铁基纳米复合粒子的比表面积大,反应活性高,应用灵活,为大多数具有挑战性的环境污染问题提供了一个有效的解决方法。 本文主要阐述了近些年来纳米零价铁及铁基纳米复合粒子在环境修复中的具体应用,同时也评估了其对环境微生物的潜在毒理效应,为以后进一步研究工作奠定一定的理论基础。

关键词: 纳米零价铁, 表面改性, 固体负载, 双金属, 毒性作用

Abstract: Since nanoscale iron particles and iron-containing nanomaterias are very effective for the transformation and detoxification of a wide variety of common environmental contaminants such as toxic metal ions, halogenated organic compounds and so on, they have been under active research in the field of environment remediation. Due to their large surface areas, high surface reactivity and application flexibility, they provide effective solutions to some of the most challenging environmental cleanup problems. In this paper, the progress of iron-containing nanomaterials and its various applications for recent years were summarized. Meanwhile, their potential microbial toxicity was also assessed, which can be a guide for further study in this research field.

Key words: nanoscale zero-valent iron, surface modification, solid support, bimetallic system,toxicity
