功能化磁性Fe3O4纳米材料去除水污染物研究进展

摘要

磁性纳米材料具有较强的化学稳定性、较高的生物相容性和良好的吸附性能,在外加磁场的作用下可迅速分离,同时还能通过表面修饰或改性等方法使其功能化,因此在去除水环境污染物方面有着广泛的应用前景.通过总结近年来的相关研究资料,综述了不同方法修饰的Fe3O4功能化磁性纳米材料在去除水污染物方面的研究进展,指出了当前研究中的主要发展方向和有待解决的问题.%Magnetic nano-materials have strong chemical stability,relatively high biocompatibility,and good adsorp-tion performance,and can be separated quickly under the action of external magnetic fields and functionalized by methods,such as surface finish or modification,etc. Therefore,they have wide application prospects of removing pol-lutants from water environment. By summarizing recent relevant research data,the research progress in terms of re-moving water pollutants by functionalized magnetic Fe3O4 nano-materials finished via different methods is summed up,and the main development directions in present research,and the problems to be solved are pointed out.
