Novel Remediation Technique for PFAS contaminated Soil and Sediment

Both chemicals Perfluorooctane Sulfonate (PFOS) and Perfluorooctanoic Acid (PFOA) are very persistent, toxic, and bio-accumulate in the environment and human body. PFAS can end up in soil from multiple sources, often mixed with other pollutants. Because of their unique lipid- and water-repellent characteristics, PFOS and PFOA are used as surface-active agents in various high-temperature applications and as a coating on surfaces that contact with strong acids or bases. It also make these materials extremely difficult to destroy. In the SBIR Phase I, QMetry in collaboration with University of Kentucky, Lexington will investigate the feasibility of a electrochemical advanced oxidation process. The composite electrode - made from ordinary materials - is chemically and physically modified such a way that it preferentially adsorbs and oxidizes PFOS and PFOA molecules. The composite electrode is benign and disposable and can be implemented in ordinary farming and construction equipment. If successful, the remediation method can be carried out in situ without extensive material and energy input or capital investment. Environmentally compatible with clean oxidant and without secondary pollutants, this method will be immensely beneficial for remediation market. The team will target semiconductor manufacturing and oil and gas industry for initial commercialization - it's current primary customers._x000D_
