Abatement Of Per- And Polyfluoroalkyl Substances With Electrochemical Oxidation, Elise Webb

Department of Environmental Studies: Undergraduate Student Theses

Throughout the United States, there is a growing concern for contamination of groundwater with harmful per- and polyfluoroalkyl substances (PFAS). These forever chemicals have no natural degradation pathways and the science community has not had any significant breakthroughs to remediate contaminated sites. Electrochemical oxidation using a boron-doped diamond (BDD) electrode shows excellent potential for becoming an effective therapy for such PFAS contaminated sites. The objective of this research is to provide proof-of-concept that electrochemical oxidation can degrade PFAS, ensure analysis is accurate, and controls of experimental design are optimal. Electrochemical oxidation degraded 10 mg/L perfluorooctanoic acid (PFOA) under a series …
