Abstract
A method for decomposing volatile organic halogenated compounds in water containing such compounds and metal ions by removing the metal ions from the water and then contacting the deionized water with a reducing agent in the presence of a catalyst. The volatile organic halogenated compounds are efficiently decomposed with a small energy requirement and low cost to eliminate, thus, making the water safe.
