Abstract

Per- and polyfluoroalkyl substances (PFASs) are persistent, toxic, and bioaccumulative chemicals requiring effective removal and detection methods. Conventional adsorbents like activated carbon and ion-exchange resins suffer from low selectivity, limited capacity, and slow kinetics, while detection methods like high-performance liquid chromatography-mass spectrometry are costly and equipment-intensive. Functional supramolecular host (FSH) materials offer a promising alternative with advantages such as host-guest molecular recognition, adaptability, and tunable structures. This review explores the application of FSHs in PFAS remediation, focusing on adsorbent structural types, adsorption kinetics, isotherms, and mechanisms, as well as regeneration strategies. It also delves into the principles of FSH-based PFAS detection systems, including their design and mechanisms. By addressing key challenges, this review provides insights for developing next-generation materials for cost-effective, efficient PFAS removal and detection in water and environmental samples.

功能超分子宿主作为检测和去除全氟烷基和多氟烷基物质的平台

全氟烷基和多氟烷基物质（PFASs）是持久性、毒性和生物蓄积性的化学物质，需要有效的去除和检测方法。传统的吸附剂，如活性炭和离子交换树脂，选择性低，容量有限，动力学慢，而检测方法，如高效液相色谱-质谱法，成本高，设备密集。功能超分子宿主（FSH）材料具有宿主-客体分子识别、适应性和结构可调等优点，是一种很有前途的替代材料。本文综述了FSHs在PFAS修复中的应用，重点介绍了吸附剂的结构类型、吸附动力学、吸附等温线、吸附机理以及再生策略。它还深入研究了基于fsh的PFAS检测系统的原理，包括它们的设计和机制。通过解决关键挑战，本综述为开发具有成本效益，高效去除和检测水和环境样品中PFAS的下一代材料提供了见解。
