摘要： PROBLEM TO BE SOLVED: To provide a method for cleaning soil, water or air by rapidly decomposing an organic halogen compound in the soil, the water or the air.
SOLUTION: The contaminated soil, water or gas is cleaned by bringing magnetite-iron combined powder containing magnetite and having 0.01-10 μm average primary diameter or a mixture of the magnetite-iron combined powder with non-iron inorganic compound powder into contact with at least one of the soil, the water or the gas contaminated with the organic halogen compound to decompose the organic halogen compound.

摘要： PROBLEM TO BE SOLVED: To provide fine composite iron powder suitable for use in a method of rapidly decomposing an organic halogen compound; composite magnetic iron powder which exhibits its function in a high frequency zone and is free from oxidation and heat generation even in the air; a production method therefor; and a wave absorber using the same.
SOLUTION: The magnetite-iron composite powder contains magnetite and has an average primary grain size of 0.01-10 μm, wherein the intensity ratio of X-ray diffraction of the magnetite to α-Fe is preferably 0.001-50, and the magnetite-iron composite powder preferably contains nickel. In the production method for the iron composite powder, when hematite powder having an average primary grain size of 0.01-10 μm is heated and reduced in a reducing gas, the reduction of the hematite powder is suspended and magnetite is incorporated into the powder. The iron composite powder is mixed with rubber and/or resin and molded.
