Perfluorinated compounds (PFCs), as emerging persistent pollutants, can exist for a long time in the environment due to their high stability. PFCs have been detected in drinking water, wastewater, and the human body. Studies have shown that PFCs pose a threat to human health and the ecological environment, which is expected to be listed in new drinking water regulations. Traditional processes, including coagulation, biological filtration, chlorination, ozonolysis, and ultraviolet light have ineffective removal efficiency on PFCs; however, advanced oxidation processes (AOP) based on ultraviolet (UV) light have good application prospects for the removal of PFCs. This study provides an overview of the removal of PFCs by UV-based AOPs; systematically introduces the research status of various UV-based AOPs from the perspectives of degradation pathways, degradation efficiency, influencing factors, formation of by-products; and comprehensively compares these different UV-based AOPs. Finally, the limitations of existing research and future research needs are discussed. This review aims to provide an overview for a better understanding of the degradation status and prospects of UV-based AOPs for the degradation of PFCs.

全氟化合物（PFCs）作为一种新兴的持久性污染物，由于其高稳定性，可以在环境中长期存在。已在饮用水、废水和人体中检测到 PFC。研究表明，PFCs对人类健康和生态环境构成威胁，有望列入新的饮用水法规。混凝、生物过滤、氯化、臭氧分解、紫外线等传统工艺对PFCs的去除效率不高；然而，基于紫外线（UV）光的高级氧化工艺（AOP）在去除 PFCs 方面具有良好的应用前景。本研究概述了基于紫外线的 AOP 去除 PFC 的情况；从降解途径的角度系统地介绍了各种基于UV的AOPs的研究现状，降解效率、影响因素、副产物的形成；并全面比较了这些不同的基于紫外线的 AOP。最后，讨论了现有研究的局限性和未来的研究需求。本综述旨在提供一个概述，以便更好地了解基于紫外线的 AOP 降解 PFC 的降解状态和前景。
