供排水系统中全氟和多氟烷基化合物(PFAS)的检测与去除研究进展
Research Progress on Determination and Removal of Per-and Polyfluoroalkyl Substances(PFAS)in Water Supply and Drainage Systems
摘要
Abstract
With the development of industry,per-and polyfluoroalkyl substances(PFAS)are being used more and more widely in daily life and production,and the impact on water environment is intensified.Due to the good water-solubility,PFAS can be migrated and transformed in the environment with the water cycle,which will ultimately affect human health.Therefore,China,Europe and the United States have begun to develop relevant standards and laws and regulations to restrict the use of PFAS.Based on a systematic summary of the sources,concentrations and transformation processes of PFAS in the water environment,detection methods such as chromatography,Total Oxidizable Precursor(TOP)assay and sensors,as well as removal technologies such as traditional physico-chemical and biochemical methods,advanced oxidation technology and incineration process are compared,aiming to provide theoretical support for the monitoring and control of PFAS.The results show that the concentration of PFAS in drinking water generally exceedes 0.1 ng/L,and there are two major limitations in the removal of PFAS in water supply and drainage processes,one is that the detection techniques could only cover a few types of PFAS,and the other is that the current removal methods can not completely eliminate the risk of PFAS,or the removal rate is poor,or it is transformed into short-chain fluoride,which triggers more potential environmental risks.关键词
