摘　　要：Fe_(3)O_(4)磁性纳米粒子是目前应用最为广泛的磁性纳米材料,相比于其他材料而言,其制备过程简单、化学稳定性好、储存方便、成本低廉,且容易实现磁性分离。Fe_(3)O_(4)磁性纳米粒子表面容易被修饰大量的含氧官能团,使其易于和其他基团连接,因此具有极大的功能化潜力。经过功能化的Fe_(3)O_(4)磁性纳米粒子具有很高的饱和磁化率以及极好的超顺磁性,从而被广泛用作水体处理过程中吸附剂、催化剂等的基质材料。本文综述了近年来具有代表性的功能化Fe_(3)O_(4)磁性纳米材料,列举了一系列功能化Fe_(3)O_(4)磁性纳米材料的制备方法以及它们在去除水体中的有机物、重金属离子、染料、抗生素等污染物方面的应用,并对磁性纳米材料在实际应用中面临的问题进行了总结和分析。Fe_(3)O_(4)magnetic nanoparticles are currently the most widely used magnetic nanomaterials.Compared with other materials,they have the advantages of simple preparation process,good chemical stability,convenient storage,low cost and easy magnetic separation.The surface of Fe_(3)O_(4)magnetic nanoparticles can be easily modified with a large number of oxygen-containing functional groups to make them easily connect with other groups,so they have great potential for functionalization.The functionalized Fe_(3)O_(4)magnetic nanoparticles exhibit high saturation magnetic susceptibility as well as excellent superparamagnetism,thus they have been widely used as substrate materials for adsorbents,catalysts,etc.,in water treatment processes.In this paper,the representative functionalized Fe_(3)O_(4)magnetic nanomaterials in recent years have been reviewed.A series of preparation methods of functionalized Fe_(3)O_(4)magnetic nanomaterials and their applications in the removal of organic matter,heavy metal ions,dyes,antibiotics and other pollutants in water have been enumerated.Furthermore,the problems in practical applications of functionalized Fe_(3)O_(4)nanomaterials are summarized and discussed.
