摘要:

吸附法是应用最为广泛且成本低廉的工业水处理方法之一。传统吸附剂因其性能单一、不易分离回收等缺点在应用中受到诸多局限。磁性纳米吸附剂因具有粒径小、比表面积大、可再生和易于固液分离等优点受到广泛关注。综述了磁性纳米吸附剂的制备方法、吸附性能及其在废水处理中的应用研究进展,以期为相关领域研究提供参考。

Abstract:

Adsorption is one of the most widely used and cost-effective methods for industrial wastewater treatment. Conventional adsorbents have many limitations in practical applications due to their shortcomings, such as single performance and difficulty in separation and recovery. At present, magnetic nano-adsorbents have attracted much attention, owing to the advantages of their small particle size, large specific surface area, reproducibility and easy solid-liquid separation. In this review, the preparation methods, adsorption properties and application of magnetic nano-adsorbents in industrial wastewater treatment were analyzed to provide references for related fields.

Key words: magnetic adsorbent, magnetic nanomaterial, wastewater treatment, adsorption
