Per- and polyfluoroalkyl substances (PFAS), commonly known as "forever chemicals", have become a major focus of current research due to their toxicity and persistence in the environment. These synthetic compounds are notoriously difficult to degrade, accumulating in water systems and posing long-term health and environmental risks. Adsorption is one of the most investigated technologies for PFAS removal. This review comprehensively reviewed the PFAS adsorption process, focusing not only on the adsorption itself, but also on the behavior of PFAS in the aquatic environment prior to adsorption because these behaviors directly affect PFAS adsorption. Significantly, this review summarized in detail the advances made in PFAS adsorption from the computational approach and emphasized the importance of integrated experimental and computational studies in gaining molecular-level understanding on the adsorption mechanisms of PFAS. Toward the end, the review identified several critical research gaps and suggested key interdisciplinary research needs for further advancing our understanding on PFAS adsorption.
全氟和多氟烷基物质（PFAS），通常被称为“永久化学物质”，由于其毒性以及在环境中的持久性，已成为当前研究的主要焦点。这些合成化合物极难降解，会在水系统中积累，并带来长期的健康和环境风险。吸附是研究最多的去除PFAS的技术之一。本综述全面回顾了PFAS的吸附过程，不仅关注吸附本身，还关注吸附前PFAS在水环境中的行为，因为这些行为直接影响PFAS的吸附。值得注意的是，本综述详细总结了从计算方法在PFAS吸附方面取得的进展，并强调了综合实验和计算研究对于在分子水平上理解PFAS吸附机制的重要性。最后，该综述指出了几个关键的研究空白，并提出了关键的跨学科研究需求，以进一步增进我们对PFAS吸附的理解。
