Description or Abstract

er- and polyfluoroalkyl substances (PFAS) are a group of synthetic compounds that have a unique structure with fluorine (F) atoms attached to carbon (C) chains. PFAS are extensively used in different industrial and commercial products resulting in their widely distribution in surface water, groundwater, soil, sediments and air. Due to their persistence in the environment and to conventional treatment processes, PFAS has recently received significant regulatory and media attention. Among the PFAS, perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) have been subjected to more intense research due to their toxicity, stability, and potential of long-range transport. Electrochemical oxidation processes have developed as promising water treatment technologies for the degradation of PFAS where an electric field is applied between special anodes and cathodes to treat the solution flowing between them. The degradation of pollutants may occur either by direct oxidation on anode's surface or by an indirect process where oxidants are formed in bulk solution This presentation will discuss our research on electrocatalytic degradation of several short and long chain PFAS.
