摘　　要：全氟化合物(PFASs)是一类具有毒性、生物累积性的难降解有机污染物,其广泛分布于全球水环境中,严重威胁到人类的健康。常规水处理技术无法有效去除PFASs,而吸附作为一种成本低、高效且操作简便的方法,常用于研究水中PFASs的去除。目前对于吸附处理水中PFASs的全面总结较少,故本文综述了近年来吸附法去除水中各种PFASs的吸附剂类型及吸附效果,归纳了主要的吸附作用机理及影响吸附过程的各种因素。最后对未来该领域的研究方向进行了展望,吸附剂再生问题、吸附法的实际应用需进一步研究。Perfluoroalkyl substances(PFASs)are a class of toxic and bioaccumulative refractory organic pollutants,which are widely distributed in the global water environment and seriously threaten human health.Conventional water treatment technologies can’t effectively remove PFASs.However,adsorption,as a low-cost,efficient and alternative method,has been often used to study the removal of PFASs in water.At present,there are few comprehensive summaries about the adsorption of PFASs in water.Therefore,this paper reviewed the adsorbents and adsorption effects of various PFASs removed by adsorption methods in recent years,summarized the main adsorption mechanism and various factors affecting the adsorption process.Finally,the future research direction in this field was prospected.The regeneration of adsorbents and the practical application of adsorption method need further study.
