View Patent ↗The present invention is directed to a method of oxidizing an organic compound present in soil, groundwater, process water or wastewater comprising contacting such organic compound with a persulfate and ferrous lactate.
1. A method of oxidizing an organic compound present in soil or groundwater comprising contacting such organic compound with a persulfate and ferrous lactate in an amount sufficient to activate the persulfate.
2. The method of claim 1 wherein the persulfate is a dipersulfate.
3. The method of claim 2 wherein the dipersulfate is sodium persulfate.
4. The method of claim 1 wherein the organic contaminant is selected from the group consisting of trichloroethylene (TCE), vinyl chloride, tetrachloroethylene (PCE), methylene chloride, 1,2-dichloroethane, 1,1,1-trichloroethane (TCA), carbon tetrachloride, chloroform, chlorobenzenes, benzene, toluene, xylene, ethyl benzene, ethylene dibromide, methyl tertiary butyl ether, polyaromatic hydrocarbons, polychlorobiphenyls, phthalates, 1,4-dioxane, nitrosodimethyl amine, and methyl tertbutyl ether.
5. The method of claim 1 wherein such method is performed in situ.
6. The method of claim 1 wherein such method is performed ex situ.
7. The method of claim 5 wherein the persulfate and ferrous lactate are added simultaneously.
8. The method of claim 5 wherein the persulfate and ferrous lactate are added sequentially.
