Treatment of Aqueous Film-Forming Foam by Heat-Activated Persulfate Under Conditions Representative of In Situ Chemical Oxidation
Poly- and perfluoroalkyl substances (PFASs) have been detected in an increasing number of water supplies. In many instances, the contamination is associated with the use of PFAS-containing aqueous film-forming foams (AFFF) in firefighting activities. To investigate the potential for remediating AFFF contamination in groundwater with heat-activated persulfate, PFAS oxidation and the generation o...
متن کاملTRACE-METAL MOBILITY DURING IN SITU CHEMICAL OXIDATION (ISCO) OF TCE BY MnO4: COLUMN EXPERIMENTS
Two series of column experiments were designed to investigate the mobility of trace metals during ISCO of TCE by MnO4 in the presence of MnOx and Fe oxyhydroxides. Results indicated that despite variable pH, concentrations of Mo, Pb, Cu, Cd and Ni are rapidly attenuated from the aqueous phase. In contrast, Zn concentrations were not significantly attenuated, except in the presence of Fe oxyhydr...
