摘　　要：介绍了基于硫酸自由基(SO4-·)的高级氧化技术在水处理领域的应用情况,叙述了不同类型非均相催化剂如钴系催化剂、锰氧化物和铁氧体等的开发和研究现状,剖析了该技术存在的局限性,虽然以Co(II)/Oxone为代表的均相系统能够高效降解有机污染物,但也存在着金属离子释放带来的健康危害等问题。因此,亟需开发新型非均相催化剂,既保持均相系统高效的催化性能,又能最大程度减少金属离子的释放;研制更加高效、稳定、方便回收的非均相催化剂是该技术的主要发展趋势。The application of sulfate radical-based advanced oxidation processes in the field of water treatment had received extensive attention. The development and research status of different heterogeneous catalysts such as cobalt-based catalysts, manganese oxideand ferrite were summarized and the limitations of this technology were also investigated. Although organic pollutants could efficiently be degraded by homogeneous process represented by Co（II）/Oxone, the leaching of metal ions may induce health problems. Therefore, it was necessary to develop new heterogeneous catalysts, which could maintain high-efficiency catalytic performance of homogeneous system, meanwhile minimizing the release of metal ions. Fabrication of heterogeneous catalysts with higher efficiency, better stability and recyelability will become the major development trend of this filed.
