全氟烷基和多氟烷基物质（PFAS）普遍存在于许多消费品中，由于其持久性，对环境造成了严重的挑战。目前，传统的水处理方法无法去除PFAS，而其他新提出的材料/技术在现实条件下使用时面临挑战。本研究报告了聚（乙烯亚胺）官能化纤维素微晶（PEI-f-CMC），其在与其在自然环境中的实际存在相关的浓度下（即，
Per- and polyfluoroalkyl substances (PFAS) are ubiquitous in many consumer products and present serious environmental challenges due to their persistent nature. Currently, conventional water treatment methods fail to remove PFAS, and other newly proposed materials/techniques face challenges when employed under realistic conditions. This study reports on poly(ethylenimine)-functionalized cellulose microcrystals (PEI-f-CMC) that showed a near-instant and high removal of PFAS under concentrations relevant to their actual occurrence in the natural environment (i.e.,
