[Advanced Purification of Per-and Polyfluoroalkyl Substances in Drinking Water： Status and Challenges].

Per-and polyfluoroalkyl substances （PFASs） are a class of emerging contaminants frequently detected in source water and drinking water. They are characterized by persistence， resistance to degradation， and various biological toxicities， posing serious risks to the environment and human health. In recent years， researchers have begun to explore ways to remove PFASs from drinking water. It is of great significance to clarify the current status and challenges of advanced purification technologies of PFASs for further research and technological innovation in this field. Based on the data-driven quantitative analysis of relevant papers， typical types， physicochemical properties， and environmental risks of PFASs were systematically categorized， and their control requirements and distribution status in surface water， groundwater， and drinking water were comprehensively reviewed. The research status and mechanism of PFASs removal technologies were analyzed， further revealing research hotspots and development trends in this field. The potential challenges were further analyzed， and the opportunities for future innovation in advanced purification technologies of PFASs were forecasted， such as the application of materials genomics， membrane separation materials based on the physical properties of water molecules， and micro/nano reactors， aiming to provide references for the efficient removal and risk reduction of PFASs in drinking water.
