摘　　要：基于自由基反应的高级氧化技术(AOPs)作为一种简单、高效、清洁的有机污染物去除技术得到了广泛研究。尖晶石型钴铁氧体(CoFe_(2)O_(4))具有催化性能好、金属浸出率低和回收再利用率高等特点,被广泛用作高级氧化过程中驱动自由基生成的催化剂。本文以尖晶石型CoFe_(2)O_(4)为研究对象,概述了CoFe_(2)O_(4)的结构与性质;归纳总结了包括形貌调控、元素掺杂、耦合复合材料在内的CoFe_(2)O_(4)改性方法;重点综述了CoFe_(2)O_(4)及其复合材料光催化氧化、非均相类芬顿氧化、过一硫酸盐氧化与臭氧催化氧化降解水中有机污染物的基本原理及研究进展;最后指出当前研究存在的问题,并对其后续研究方向进行展望。Advanced oxidation technologies(AOPs),which based on free radical reactions,have been widely investigated as a simple,efficient and clean technology for the removal of organic pollutants.Spinel-type cobalt ferrite(CoFe_(2)O_(4))is widely used as a catalyst for driving radical generation in advanced oxidation processes due to its good catalytic performance,low metal leaching rate and high recycling rate.This review takes spinel-type CoFe_(2)O_(4) as the research object.Herein,the structure and properties of CoFe_(2)O_(4) are outlined.The modification methods of CoFe_(2)O_(4),including morphology modification,elemental doping and coupling composite materials,are summarized.The basic principles and research progress of photocatalytic oxidation of CoFe_(2)O_(4) and its composites,non-homogeneous Fenton-like oxidation,peroxydisulfate oxidation and ozone-catalyzed oxidation for the degradation of organic pollutants in water are highlighted.Finally,the problems of the current study are pointed out and the direction of its subsequent research is envisioned.
