摘要
全氟及多氟烷基化合物(PFASs)是一类在水源水和饮用水中频繁检出的新污染物,具有持久性、难降解性和多种生物毒性,对环境与人体健康构成严重威胁.近年来,研究者开始着力探索饮用水中PFASs的去除方法.厘清当前PFASs深度净化技术的现状与挑战,对于该领域的进一步研究和技术创新具有重要意义.基于对相关论文的数据驱动定量分析,系统总结了典型PFASs的种类及理化性质和环境风险,综述了它们的管控要求及在地表水、地下水及饮用水中的分布现状;分析了PFASs深度去除技术的研究现状和去除机制,挖掘该领域的研究热点和发展趋势.深入剖析了PFASs深度净化技术面临的潜在挑战,并从材料基因组学应用、基于水分子物性的膜分离材料及微/纳米反应器等方面展望了未来PFASs深度净化技术创新的机遇,以期为饮用水中PFASs高效去除和风险削减提供参考借鉴.
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.
