Reusable granules suck harmful PFAS 'forever chemicals' out of water

摘要

GRANULES that selectively target and extract harmful "forever chemicals" from water could help clean up pollution. Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are a class of synthetic chemicals widely used in coatings and foams that resist oil, heat and water. There are thousands of types of PFAS, used in everything from dental floss to waterproof jackets and non-stick pans.
