Comparative Study on Degradation Methods of Per- and Polyfluoroalkyl Compounds in Water
Summary
This study reviews and compares methods for degrading per- and polyfluoroalkyl substances (PFAS) in water, examining photocatalysis, activated carbon adsorption, and advanced oxidation processes, finding that each approach has distinct trade-offs in efficacy and applicability depending on the type of water body being treated.
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.
