There has also been recent interest in and some field applications using sodium persulfate (Na2S2O8) to oxidize organic contaminants or to reduce the oxidant demand of native soils before other oxidants are applied to the contamination. Some research has demonstrated that when mixed with ferrous iron as a catalyst, the sulfate free radical (SO4 - ) can be produced, which has an oxidation potential only slightly less than Fenton's Reagent. Field testing of this oxidant to date has primarily involved the destruction of chlorinated organics rather than petroleum hydrocarbons. Given the experimental status of this oxidant, it is not further described or discussed in this chapter.
