摘要： 新污染物(Emerging Contaminants, ECs)具有结构稳定且浓度低的特点,传统污水处理工艺难以完全去除，这对水生态环境和人类健康构成潜在威胁。高级氧化技术(Advanced Oxidation Process, AOPs)可以快速有效地降解持久性污染物，但对于真实水体环境中的微量ECs，AOPs需要过量的氧化剂或消耗更多的能源，使水处理成本大幅提升，甚至导致二次污染。因此，开发高效且低能耗的选择性氧化工艺对处理水中ECs具有现实意义。靶向吸附-转化技术能够有效提高自由基的利用率，高效去除微量、难降解新污染物。本文首先系统性地阐述了水清洁技术中选择性氧化策略的理念，着重介绍了电吸附-转化高效能选择性去除复杂水体中全氟和多氟烷基物质(Per-and Polyfluoroalkyl Substances, PFAS)的技术特点与发展现状，最后对未来的研究方向与趋势进行了展望。

Abstract: Emerging contaminants (ECs) are characterized by stable structures and low concentrations, making them difficult to remove completely using traditional wastewater treatment processes. ECs are posing potential risks to aquatic ecosystems and human health. Advanced oxidation processes (AOPs) can rapidly and effectively degrade persistent pollutants. However, for trace refractory ECs in real water matrices, AOPs require excessive oxidants or consume more energy, resulting in low cost-effectiveness of water treatment and even secondary pollution. Therefore, developing efficient and low-energy selective oxidation processes for treating trace ECs in water has practical significance. Targeted adsorption-transformation technology can effectively enhance the utilization of free radicals and efficiently remove trace ECs. The concept of advanced water purification processes is elaborated based on selective oxidation, with a focus on the technical characteristics and recent development of selective electrochemical adsorption-transformation technology to remove per- and polyfluoroalkyl substances (PFAS) from water. Finally, an outlook is provided on the future research directions and trends.

Key words: emerging contaminants, selective oxidation, targeted adsorption-transformation technology, redox polymer, PFAS(Per-and Polyfluoroalkyl Substances)
