多孔材料吸附全氟烷基化合物的应用进展OA北大核心CSTPCD
Research progress of porous materials for perfluoroalkyl substances adsorption
全氟烷基化合物(PFASs)属于新兴有机污染物的范畴,自身具有毒性、生物累积性且难降解,其广泛分布于全球水环境中,严重威胁着生态平衡与人类健康.吸附法作为一种物理化学方法,其成本低、能耗低、效率高且操作简便,常用于水体中PFASs的去除,然而目前有关水体中PFASs的吸附去除的全面总结较少.从吸附剂角度出发,首先归纳总结了近年来用于水体中PFASs吸附去除的各类多孔材料吸附剂,然后对主要吸附作用机制及影响吸附效果的关键因素进行梳理分析,最后对这一领域未来的发展方向及前景进行展望.
Perfluoroalkyl substances(PFASs)are a class of emerging organic pollutants with toxicity,bioaccumulation and refractory,which are widely distributed in the global water environment and seriously threaten ecological balance and human health.As a physicochemical method,adsorption technology was widely used for PFASs removal from water due to its low cost,low energy consumption,high efficiency and simple operation.However,there were few comprehensive summaries about PFASs adsorption from water.Therefore,this review outlines different porous materials and their adsorption performance for various PFASs removal in recent years.Subsequently,the main adsorption mechanism and various factors affecting adsorption process are summarized.Finally,future research direction and application prospect in this field are proposed.
