“Researchers have created a molecular nanocage that captures the bulk of per- and polyfluoroalkyl substances, or PFAS, found in water—and it works better than traditional filtering techniques that use activated carbon. Made of organic nanoporous material designed to capture only PFAS, this tiny chemical-based filtration system removed 80 to 90% of PFAS from sewage and groundwater during the study, respectively, while showing very low adverse environmental effects.
The study was led by scientists at the University at Buffalo and published in ACS ES&T Engineering.
PFAS are chemical compounds sometimes called ‘forever chemicals’ and are commonly used in food packaging, nonstick coatings and other applications. PFAS do not degrade easily and are notoriously difficult to remove from water sources.” …
