Researchers at the University of Bath have published a report in Chemical Engineering Journal about a method that removes at least 75% of perfluorooctanoic acid (PFOA) from water using ceramic-infused lattices (or ‘monoliths’). PFOA is one of the two commonest perfluoroalkyl and polyfluoroalkyl substances (PFAS). These are under increasing scrutiny as ‘forever chemicals’ that take hundreds of years to degrade and are linked to health issues like harm to reproductive, developmental and cardiovascular systems.
