Per- and polyfluorinated alkyl substances (PFASs) contaminate groundwater, surface water, and finished drinking water internationally. Their ecological persistence and adverse human health effects demand effective remediation approaches. Motivated by the limitations in selectivity and performance of current PFAS removal technologies, we report a platform approach for the development of ionic fluorogel resins that effectively remove a chemically diverse mixture of PFAS from water. The synthesis of a material library with systematic variation in fluorous and ionic components led to the identification of a resin that demonstrated rapid removal of PFASs with high affinity and selectivity in the presence of nonfluorous contaminants commonly found in groundwater. The material can be regenerated and reused multiple times. We demonstrate ionic fluorogels as effective adsorbents for the removal of 21 legacy and emerging PFASs from settled water collected at the Sweeney Water Treatment Plant in Wilmington, North Carolina.

用于修复水中的全氟和多氟烷基物质的离子氟凝胶。

全氟烷基物质和多氟烷基物质 (PFAS) 在全球范围内污染地下水、地表水和成品饮用水。它们的生态持久性和对人类健康的不利影响需要有效的补救方法。受当前 PFAS 去除技术的选择性和性能限制，我们报告了一种开发离子氟凝胶树脂的平台方法，该树脂可有效去除水中化学成分多样的 PFAS 混合物。氟和离子成分系统变化的材料库的合成导致了一种树脂的鉴定，该树脂能够在地下水中常见的非氟污染物存在的情况下以高亲和力和选择性快速去除 PFAS。该材料可以再生并重复使用多次。我们证明离子氟凝胶作为有效的吸附剂，可以从北卡罗来纳州威尔明顿斯威尼水处理厂收集的沉淀水中去除 21 种遗留和新出现的 PFAS。
