Abstract
Per- and polyfluoroalkyl substances (PFAS) are ubiquitously present and persistent in the environment and show potential to cause detrimental health effects in humans. The removal and destruction of PFAS is a new and significant problem, and discovering methods for treating PFAS contamination is a burgeoning field. In this work, methods including Ion Exchange Resins (IXRs) and Electrochemical Oxidation (EO) were utilized and combined to enhance the removal and destruction of Per- and polyfluoroalkyl substances (PFAS) in water. A regenerable, multi-use IXR and EO were combined into a closed loop system to minimize waste discharge and maximize PFAS breakdown. This process includes a newly developed resin regeneration solution to ensure a high degree of PFAS elution while also containing being able to undergo EO effectively.
