Description
Amit Kumar and co-authors wrote a 2026 study on breaking down PFOS, a stubborn pollutant from the PFAS chemical family, in tap water. Its carbon-fluorine bonds resist normal water treatment, which only traps the chemical. Their method uses cold plasma, an energised gas, helped by bubbling air through the water.
The plasma makes a mix of reactive species that attack PFOS at the water surface. With air bubbling, the system destroyed 99.99 percent of PFOS at high starting levels and freed about 35 percent of its fluorine. Breakdown followed a fast pattern, with half the PFOS gone in about 1.6 minutes. Step-by-step products showed a chain of shorter fragments. The authors present the method as a chemical-free option for PFAS cleanup.
