Impact/Purpose:
The environmental or health problem addressed by the study: Selectivity with respect to chloride was estimated for nine drinking water perfluoroalkyl chemicals and three strong base anion exchange resins. A general description of the work and results: Selectivity with respect to chloride was determined for nine drinking water relevant per- and polyfluoroalkyl substances (PFAS): perfluoro-2-propoxypropanoic acid (GenX), five perfluoroalkyl carboxylic acids (PFCAs), and three perfluoroalkyl sulfonic acids (PFSAs). Three single-use strong base anion exchange gel resins were investigated, targeting drinking water relevant equilibrium PFAS liquid concentrations (≤ 500 ng/L). The long-term importance or significance of the findings: Estimated selectivity values allow future extension and validation of an open-source ion exchange column model. Who would be interested in or could apply the results (e.g. program or regional partners, general public, local communities): Researchers, regions, engineering, and drinking water utilities trying to remove PFAS from drinking water.
