磁性纳米颗粒表面功能化修饰及其在污水处理中的应用进展

Research progress on functional modification on magnetic nanoparticle surface and its application in wastewater treatment

磁性纳米颗粒具有高比表面积、高表面能和高磁响应等特性,其作为磁性吸附剂载体在污水处理中有着巨大的应用潜力,但目前的制备工艺及成本尚难以达到污水处理工业化应用要求。在总结磁性纳米吸附材料改性方法的基础上,综述了功能化磁性纳米颗粒在去除含重金属、有机污染物、无机污染物等污水中的应用研究进展,并对未来的磁性纳米吸附材料研究方向提出了若干建议。

Magnetic nanoparticles were characterized by high specific surface area,high surface energy,and high magnetic response.As magnetic adsorbent carriers,they are very likely to be used for disposal of wastewater.How-ever,the current technology and cost for preparation of the magnetic nanoparticles are hardly acceptable for the industrial purpose in the domain of wastewater treatment.Based on the modification approaches of magnetic nano-adsorption materials,in this paper research progress on application of functional magnetic nanoparticles in the removal of heavy metals,organic pollutants,inorganic pollutants and others contained in the waste water were reviewed.Some recommendations on future research interests of magnetic nano-adsorption materials were presented.
