全氟或多氟烷基化合物(PFAS)具有持久性、生物累积性和潜在生物毒性,在水环境中被广泛检出。吸附作为有效的PFAS处理技术具有低成本、易操作等优点。活性炭和树脂是较为常用的PFAS吸附剂。总结了活性炭和树脂改性前后对PFAS的吸附性能,介绍了其吸附机理。结合目前吸附去除水环境中PFAS的研究进展,展望了吸附法用于水中PFAS处理的发展方向,为进一步开发高效、实用的PFAS吸附去除技术提供参考。

Perfluoroalkyl and polyfluoroalkyl substances (PFAS) have general persistence,bioaccumulation,and potential bio-toxicity,and are widely detected in the aquatic environment.Adsorption,as an effective PFAS treatment technology,has the advantages of low cost and easy operation.Activated carbon and resins are commonly used for PFAS adsorbents.In this paper,the adsorption performance of PFAS on activated carbon/resin before and after modification is summarized,and the related adsorption mechanism is introduced.Based on the current research progress on adsorption to remove PFAS in the aqueous environment,the development direction of adsorption for PFAS treatment in water is prospected.This work can provide some references and basis for further development of highly efficient and practical PFAS removal methods.
