Researchers develop PFAS-destroying membrane

TEMPE — Researchers at Arizona State University have developed a membrane technology that captures per- and polyfluoroalkyl substances (PFAS) in water and chemically destroys them, rather than transferring the pollutants to filters or waste.

The system uses hollow membrane fibres coated with palladium nanoparticles. Hydrogen gas passes through the fibres, where palladium converts it into a reactive form that strips fluorine from PFAS molecules.
