摘　　要：磁性纳米材料作为一个快速发展的领域,其应用已经渗透到生产生活的方方面面。由于表面积大、表面可功能化、易回收等优越的物理化学性能,磁性纳米材料在污水处理等方面的应用越来越受到关注。在去除水污染物方面,磁性纳米粒子(MNPs)吸附速度快、去除效率高、易分离,与传统吸附剂相比,表现出了极大的优越性。重点介绍了MNPs在污水净化,包括重金属离子的吸附、染料、农药的去除及其他有机化合物降解中的重要应用。As a rapidly developing field, the application of magnetic nanomaterials has penetrated into all aspects of production and life. Due to its advantages such as large surface area, surface functionalization, and easy recovery, it has attracted increasing attention in wastewater treatment. In the removal of water pollutants, the magnetic nanoparticles （MNPs） have a fast adsorption rate, high removal efficiency, and easy separation properties. Compared with traditional adsorbents, they show great superiority. This study focused on the important applications of MNPs in wastewater purification, including adsorption of heavy metal ions, removal of dyes, pesticides, and degradation of other organic compounds.
