Combined Ion Exchange-Reduction Process for the Elimination of Fluorinated Contaminants in Waters
Per- and polyfluoroalkyl substances (PFAS) are stable organic chemicals, which have been used in a variety of products such as surfactants, fire retardants and paints. The wide application of PFAS have caused contamination of environment and PFAS can cause many types of diseases in humans.
This project will investigate the combination of ion exchange/desorption and reductive UV/sulfite degradation for PFAS elimination in contaminated waters such as groundwater. The project advances our understanding of ion exchange and desorption behaviour of PFAS and their substitutes on anion exchange resins as well as their degradation efficiencies in complex water matrices. Study is also expected to provide novel insights into PFAS degradation mechanisms. The project is led by Dr. Tiina Leiviskä.
