概要	Herein, we present an approach for the room-temperature defluorination of PTFE using sodium dispersion, enabling the conversion of PTFE into sodium fluoride (NaF) under mild conditions. This method not only eliminates the need for elevated temperatures, but also demonstrates high yields of fluoride ion recovery, reaching up to 97% under optimized conditions. We further extend the application of this method to non-polymer, per- and polyfluoroalkyl substances (PFAS), including perfluorononanoic acid (PFNA), perfluorooctanoic acid (PFOA), perfluorobutanesulfonic acid (PFBS) and trifluoroacetic acid (TFA), achieving similarly high yields of NaF with appropriate adjustments of the reaction time and reagent amounts.
