Per- and poly-fluoroalkyl substances (PFAS) have gained widespread attention due to their adverse effects on health and environment. Developing efficient technology to capture PFAS from contaminated sources remains a great challenge. In this study, we introduce a type of reusable polymeric sorbent (PFPE-IEX + ) for rapid, efficient, and selective removal of multiple PFAS impurities from various contaminated water sources. The resin achieves >98% removal efficiency ([PFPE-IEX + ] = 0.5-5 mg mL, [PFAS] = 1-10 ppb in potable water and landfill leachate) and >500 mg g sorption capacity for the 11 types of examined PFAS. We achieve efficient PFAS removal without breakthrough and subsequent resin regeneration and demonstrate good PFAS recovery in a proof-of-concept cartridge setup. The outcomes of this study offer valuable guidance to the design of platforms for efficient and selective PFAS capture from contaminated water, such as drinking water and landfill leachate.
全氟和多氟烷基物质（PFAS）因其对健康和环境的不利影响而受到广泛关注。开发从受污染源头捕获PFAS的高效技术仍然是一项巨大挑战。在本研究中，我们引入了一种可重复使用的聚合物吸附剂（PFPE-IEX+），用于从各种受污染水源中快速、高效且选择性地去除多种PFAS杂质。该树脂对11种检测的PFAS实现了>98%的去除效率（[PFPE-IEX+]=0.5-5mg/mL，饮用水和垃圾渗滤液中[PFAS]=1-10ppb）以及>500mg/g的吸附容量。我们实现了高效去除PFAS且无穿透现象以及随后的树脂再生，并在概念验证滤芯装置中证明了良好的PFAS回收率。本研究结果为设计从受污染水体（如饮用水和垃圾渗滤液）中高效、选择性捕获PFAS的平台提供了有价值的指导。
