摘　　要：六价铬(Cr(Ⅵ))具有生物积累性、生物持久性和剧毒性三大特性,是致癌、致畸、致突变的“三致”污染物,严重危害生态环境和人类健康.随着工业化的迅速发展,含Cr(Ⅵ)废水的排放日益增多,Cr(Ⅵ)污染日趋严重,必须对其进行无害化处理.尖晶石型铁氧体具有吸附;催化还原Cr(Ⅵ)的能力和特殊的磁分离性能,是一种重要的Cr(Ⅵ)无害化处理材料.本文综述了尖晶石型铁氧体在Cr(Ⅵ)无害化处理领域的应用现状,并展望了今后的研究重点和发展方向,以期为含Cr(Ⅵ)废水的无害化处理及绿色工业的发展提供建议.Hexavalent chromium(Cr(Ⅵ))is a highly toxic inorganic pollutant with the characteristics of bioaccumulation,biopersistence and high toxicity,and has strong carcinogenic,teratogenic and mutagenic effects on ecological environment and human health.With the rapid development of industrialization,the discharge of Cr(Ⅵ)-containing wastewater is gradually increasing,causing more and more serious Cr(Ⅵ)pollution,which has become a great threat to the human society.Removal of the toxic Cr(Ⅵ)is becoming an urgently task to be solved and has attracted more and more attention.Spinel ferrites,which possess adsorption and catalytic degradation ability of Cr(Ⅵ)and magnetic separation nature,are considered as the most promising candidates for harmless treatment of Cr(Ⅵ)-containing wastewater.Some research results and development directions of spinel ferrites used for Cr(Ⅵ)removal in the future are prospected in present paper.We hope this review will provide some useful guidance for the harmless treatment of Cr(Ⅵ)-containing wastewater,and arouse more attention to the development of green industry.
