Comparative Study on Degradation Methods of Per- and Polyfluoroalkyl Compounds in Water

Abstract. This article aims to explore the degradation methods of per- and polyfluoroalkyl compounds (PFASs) in water bodies, and analyze the principles, advantages and disadvantages of different degradation methods and their application effects in different types of water bodies. In view of the wide application, long half-life, high mobility and potential harm to the ecological environment and biological health of PFASs, it is of great significance to study their effective degradation methods. By reviewing the existing literature, this article lists several major PFASs degradation methods, such as photocatalysis, activated carbon adsorption, and advanced oxidation, and compares their performance characteristics, which provides a scientific basis for the control of PFASs pollution in water bodies.
