摘　　要：纳米铁氧体材料作为吸附剂在污水处理中的应用具有操作简单、吸附量大及易回收等优点,但单一的纳米铁氧体材料吸附容量有限,因此对纳米铁氧体材料进行改性尤为必要。在概述铁氧体材料类型和制备方法、纳米铁氧体材料结构和性能的基础上,着重从复合改性方面综述了纳米铁氧体复合材料的研究进展及其在吸附污水中重金属、有机物、无机物等方面的应用进展,指出复合功能化材料可以大大改善纳米铁氧体材料的磁性和吸附性能,并对纳米铁氧体复合材料的发展趋势进行了展望。The application of nano-ferrite materials as adsorbents in wastewater treatment has the advantages of simple operation,high adsorption capacity,and easy recovery,but the adsorption capacity for single nano-ferrite material is limited.Therefore,it is particularly necessary to modify nano-ferrite materials.On the basis of summarizing the types and preparation methods of ferrite materials,the structure and properties of nano-ferrite materials,we review the research progress of nano-ferrite composite materials and their application in the adsorption of heavy metals,organic substances,and inorganic substances in wastewater.Moreover,we point out that composite functional materials can greatly improve the magnetic and adsorption performance of nano-ferrite composite materials.Furthermore,we put forward prospects for the development trend of nano-ferrite composite materials.
