Per- and polyfluoroalkyl substances (PFAS) are highly toxic pollutants of significant concern as they are being detected in water, air, fish and soil. They are extremely persistent and accumulate in plant and animal tissues. Traditional methods of detection and removal of these substances use specialised instrumentation and require a trained technical resource for operation. Molecularly imprinted polymers (MIPs), polymeric materials with predetermined selectivity for a target molecule, have recently begun to be exploited in technologies for the selective removal and monitoring of PFAS in environmental waters. This review offers a comprehensive overview of recent developments in MIPs, both as adsorbents for PFAS removal and sensors that selectively detect PFAS at environmentally-relevant concentrations. PFAS-MIP adsorbents are classified according to their method of preparation (e.g., bulk or precipitation polymerization, surface imprinting), while PFAS-MIP sensing materials are described and discussed according to the transduction methods used (e.g., electrochemical, optical). This review aims to comprehensively discuss the PFAS-MIP research field. The efficacy and challenges facing the different applications of these materials in environmental water applications are discussed, as well as a perspective on challenges for this field that need to be overcome before exploitation of the technology can be fully realised.
全氟和多氟烷基物质（PFAS）是备受关注的剧毒污染物，因为它们在水、空气、鱼类和土壤中都有被检测到。它们极其持久，并会在动植物组织中积累。检测和去除这些物质的传统方法需要使用专门的仪器设备，并且需要训练有素的技术人员来操作。分子印迹聚合物（MIP）是对目标分子具有预定选择性的聚合材料，最近已开始被应用于环境水体中PFAS的选择性去除和监测技术。本综述全面概述了MIP的最新进展，包括作为去除PFAS的吸附剂以及在环境相关浓度下选择性检测PFAS的传感器。PFAS-MIP吸附剂根据其制备方法（如本体聚合或沉淀聚合、表面印迹）进行分类，而PFAS-MIP传感材料则根据所使用的传感方法（如电化学、光学）进行描述和讨论。本综述旨在全面探讨PFAS-MIP研究领域。讨论了这些材料在环境水应用中不同应用面临的功效和挑战，以及在该技术能够充分实现应用之前该领域需要克服的挑战的展望。
