摘要
纳米铁具有比表面积大、颗粒体积小、表面活性强、易与改性材料复合等优点,但表面易被氧化、反应过程易团聚,进而严重影响其反应活性,因此引入改性功能材料能有效的对纳米铁表面功能化修饰,克服纳米铁不足之处。主要涉及两方面内容,其一介绍纳米铁的制备方法,重点介绍植物还原法制备纳米铁,并比较其优缺点,其二总结纳米铁各改性材料性能,探究各类负载型纳米材料对水体污染物去除效果。最后对纳米铁制备方法及改性材料选取提出合理建议,为从事相关领域研究人员提供理论参考。
Nano iron has a large specific surface area,small particle volume,strong surface activity,and easy to compound with modified materials,but the surface is easy to be oxidized and the reaction process is easy to aggregate,thus seriously affecting its reactivity.Therefore,the introduction of modified functional materials can effectively modify the surface functionalization of nano-iron and overcome its shortcomings.This paper mainly introduced two main aspects:one was the preparation method of nano-iron,focusing on the plant reduction method and comparing its advantages and disadvantages;the other was the summary of the properties of various modified materials of nano-iron and the removal effect of various supported nano-materials on water pollutants.Finally,reasonable suggestions were put forward on the preparation method of nano iron and the selection of modified materials,which could provide theoretical references for researchers in related fields.
