摘要:
众所周知,纳米颗粒在去除水中污染物的过程中易团聚,还会造成水体的二次污染。磁性Fe3O4纳米颗粒因其能迅速从水中分离的特性而被广泛关注。改性之后的磁性Fe3O4纳米颗粒在水中污染物的去除方面有很好的应用。对磁性Fe3O4纳米颗粒及其载体或复合物的制备方法进行了概述,重点对水中污染物的去除从3个方面进行了阐述:磁性Fe3O4纳米材料对水中重金属的吸附、有机物的吸附及水中细菌和医疗废物的处理。

Abstract:
As we all know,nanoparticles usually agglomerate while removing contaminants from water,which can cause secondary pollution.Therefore,magnetic Fe3O4nanoparticles have attractted more attentions due to that it can be separated from water with an outer magnet.Recently,modified magnetic Fe3O4 nanoparticles have been used to clean polluted water.Herein,several research progresses about magnetic Fe3O4 nanoparticles were reviewed in detailed,such as the preparation methods,modification technologies,and their environmental applications.Futhermore,three important highlights for cleaning water environmental were also discussed,such as the adsorption of heavy metals and organic matter,the treatment of bacteria and medical waste in water.
