Charged microdroplets enable mineralization of persistent PFAS pollutants – New Study/Science Updates



Anthropogenic perfluoroalkyl and polyfluoroalkyl substances (PFAS) are widespread and persistent pollutants that are increasingly subject to stringent regulatory thresholds in water resources. Current nonthermal defluorination strategies have limitations including incomplete mineralization, leaving behind short-chain PFAS byproducts and residual fluoride ions, thereby posing challenges to meeting water quality standards.



Summary

Anthropogenic PFAS are pervasive pollutants in water, facing increasingly strict regulations. Current non-thermal methods to remove them, like defluorination, have drawbacks. These strategies often fail to completely break down the PFAS, resulting in the creation of shorter-chain PFAS and leftover fluoride. This incomplete mineralization presents obstacles in achieving the required water quality standards, necessitating improved treatment technologies.
