Molecular nanocages remove 80-90% of PFAS, or ‘forever chemicals,’ from water

Researchers funded by the U.S. National Science Foundation 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 American Chemical Society 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. Studies show exposure to PFAS may cause a range of negative health impacts, including decreased fertility, developmental delays in children and increased risk for some cancers. The safe and effective removal of PFAS from groundwater, sewage and other water sources is a national challenge.

Molecular nanocages have been previously suggested as candidates for pollutant removal, including for PFAS. Their sturdy structures provide capabilities to capture, remove and chemically deactivate hazardous substances like PFAS and many others. They could also potentially filter out noxious gases from the air, the study authors say.
