PROBLEM TO BE SOLVED: To improve decomposition velocity even if large amounts of water soluble metal salts not are mixed, when the water soluble metal salts are mixed in the decomposition of an organic halide with iron powder. SOLUTION: The organic halide is decomposed and purified for a short time by mixing an extremely minute amount of nickel sulfate and/or nickel chloride in an iron powder with soil contaminated with the organic halide, wastewater, or underwater. Less than 0.1 wt.% of nickel sulfate and/or nickel chloride to the amount of the iron powder is used. It is preferable that the mixed amount of the iron powder is in a scope of 0.1-10 wt.% to the soil. COPYRIGHT: (C)2010,JPO&INPIT |
