Improved treatment of per- and polyfluoroalkyl substances (PFAS) in water is critically important light the proposed United States Environmental Protection Agency (USEPA) drinking regulations at ng L−1 levels. The addition peroxymonosulfate (PMS) during electrochemical oxidation (EO) can remove destroy PFAS, but levels have not been tested, PMS itself be toxic. objective this research was to test peroxydisulfate (PDS, an alternative PMS) activation by boron-doped diamond (BDD) electrodes for level perfluorooctanoic acid (PFOA) degradation. influence PDS concentration, temperature, real matrix effects, PFOA concentration on PDS-EO performance were systematically examined. Batch reactor experiments revealed that 99.8 % degraded 69.1 defluorination achieved, confirming mineralization. Scavenging implied sulfate radicals (SO4–) played a more role degradation than HO, 1O2, or electrons (e−). Further identification transformation products liquid chromatography-mass spectrum (LC-MS) analysis established plausible pathways. corroborates direct electron transfers electrode initiate SO4– improves overall cleaving CC bond between C7F15 COOH moieties PFOA, leading possible such as F−. perfluoroalkyl oxidized resulting formation shorter chain perfluorocarboxylic acids (e.g., perfluorobutanoic [PFBA]), with eventual mineralization CO2 At environmentally relevant low initial 100 99 achieved. slightly affected less removal observed river sample (91 %) compared tests conducted Milli-Q (99 %). Overall, EO provided destructive approach elimination PFOA.
