摘　　要：Heterogeneous iron-based catalysts have drawn increasing attention in the advanced oxidation of persulfates due to their abundance in nature,the lack of secondary pollution to the environment,and their low cost over the last a few years.In this paper,the latest progress in the research on the activation of persulfate by heterogeneous iron-based catalysts is reviewed from two aspects,in terms of synthesized catalysts(Fe0,Fe_(2)O_(3),Fe_(3)O_(4),FeOOH)and natural iron ore catalysts(pyrite,magnetite,hematite,siderite,goethite,ferrohydrite,ilmenite and lepidocrocite)focusing on efforts made to improve the performance of catalysts.The advantages and disadvantages of the synthesized catalysts and natural iron ore were summarized.Particular interests were paid to the activation mechanisms in the catalyst/PS/pollutant system for removal of organic pollutants.Future research challenges in the context of field application were also discussed.
