Polytetrafluoroethylene recycling using the sodium dispersion-based defluorination method (IMAGE)
Caption
The disposal of spent Polytetrafluoroethylene (PTFE) and polyfluoroalkyl substances often requires energy-intensive processes, extreme temperatures, and complex reagents. Now, researchers have proposed an alternative defluorination approach that utilizes sodium dispersion to recover fluorine in the form of sodium fluoride (NaF) with a yield of up to 98%. The recovered NaF can be recycled, enhancing fluoride resource utilization.
