| Abstract: | Because of its stability, persistence, and biological accumulation in environmental media, Perfluorinated compounds(PFCs)caused extensive research around the world.Based on the analysis of the distribution characteristics of perfluorinated compoundspollution in surface water, it is concluded that the perfluorinated compounds in surface water mainly exist in the form of PFOS and PFOA.In this paper, the degradation mechanism of different catalysts in the photocatalytic degradation of typical perfluorinated compounds in surface water was discussed.The general process of photocatalytic degradation and the advantages and disadvantages of different research methods are summarized, and in this paper, the author puts forward the development trend of the typical perfluorinated compounds in surface water. |
