There is evidence showing that human activities have resulted in the ubiquitous contamination of the environment with perfluorochemicals (PFCs). The purpose of this research is to assist in the development a predictable and low cost in situ treatment train for remediating PFC contaminated groundwater. The treatment train involves first the sorption of onto granular activated carbon (GAC), followed by treatment and regeneration of the GAC using activated persulfate. The sorption capacity for PFCs tested to date include: Jacobi Carbon (type 6), F400 Carbon (type 4), and Coconut based carbons (type 7). In this research the impact of pretreatment of these carbons with HCl, NaOH, and hydrogen peroxide catalyzed with Fe(III) on their sorption capacity was investigated. It was found that the sorption of PFHxS and PFOA depended upon the concentration of the wastewater, the type of AC used, and the pretreatment methods. Of the methods tested, NaOH was the most effective (as hypothesized) for increasing the sorption capacity of the carbons.
