Research Progress on Occurrence Characteristics and Removal Technology of Perfluorinated and Polyfluoroalkyl Substances in Water
In view of the increasingly serious and difficult removal of perfluorinated and polyfluoroalkyl substances(PFASs)in water environment,the occurrence characteristics and removal technologies of PFASs in water environment were reviewed,including the pollution status,environmental behavior,ecological risks and pollution removal technolo-gies.The advantages and disadvantages of adsorption method,ultrasonic degradation method,photochemical method,electrochemical oxidation method and microbial degradation method for removing PFASs in water environment were sum-marized.It is suggested that future researches will focus on applying the removal technology in combination based on the environmental behavior characteristics of PFASs.
