A cheaper way to fight 'forever chemicals': How pH-controlled traps could clean drinking water

Forever chemicals don’t break down and don’t disappear, but Florida International University scientists have developed a safer, cheaper, and reusable solution that could remove these chemicals. FIU chemistry professor Kevin O’Shea and chemistry Ph.D. candidate Rodrigo Restrepo Osorio have created a new cleanup approach that captures and releases PFAS chemicals on demand by using water’s own pH level.
