Poly‐ and perfluoroalkyl substances (PFASs) are man made chemicals consisting of over 3,000 individual compounds. As they are extremely persistent, bioaccumulative and the possible toxicity to human and wildlife, more attention was given to regulate water quality due to PFAS contamination. Adsorption technology using Granular Activated Carbon (GAC) followed by thermal regeneration is a current, widly used technique inaddition to Ion exchange resins. However, thermal regeneration requires high energy, and considerable carbon loss in each regeneration attempt are the major drawbacks. Therefore, in this project, alternative adsorption technique using commercially available Expendable Graphite (EG) to remove PFASs in groundwater, then regenerate the EG by breaking down the PFASs using Electrochemical oxidation process simultaneously, which may be more efficient and cost effective than other currently available PFAS treatment technologies.
