Persulfate oxidation chemistry is an emerging technology for the in situ chemical oxidation of chlorinated and non-chlorinated organics. Activation of persulfate to form sulfate radicals is a potent tool for the remediation of a wide variety of contaminants, including chlorinated solvents (ethane and methane), BTEX, MTBE, 1,4-dioxane, PCB’s and PAH’s. Several new activation technologies now exist to catalyze the formation of sulfate radicals, including persulfate combined with chelated-metal complexes, persulfate combined with hydrogen peroxide and alkaline persulfate. The breadth of activator systems allows for the proper choice of persulfate technology for given contaminants and site conditions.
