  "abstract": "Fluorochemicals are widely used in modern society due to their unique and valuable properties. From the perspective of sustainable fluorine resource utilization, technologies that enable the recovery and reuse of fluorine from waste or captured fluorochemicals are crucial. However, efficient strategies for recovering fluorine from these materials remain limited. Herein, we report a mechanochemical strategy for the direct conversion of activated carbon-adsorbed PFAS and fluorinated gases into potassium fluoride (KF), a valuable fluorination reagent, by ball milling with potassium metal. The process proceeds rapidly and efficiently under solvent-free conditions. The method is applicable to a variety of PFAS, including perfluorooctanoic acid (PFOA), perfluoroheptanoic acid (PFHpA), and perfluorobutanesulfonic acid (PFBS), as well as fluorinated gases such as SF6, HFC-125, and HFC-23. This work provides a sustainable strategy toward a fluoro-circular economy through the recovery of fluorine as a valuable chemical resource.",
