Claims (12)

1. A process for producing an organic compound decomposing agent which comprises:

obtaining a fine particle iron suboxide by neutralizing waste sulfuric acid which contains iron compounds, wherein said iron suboxide is berthollide, and

admixturing the fine particle iron suboxide with a fine particle iron.

2. A process for producing an organic compound decomposing agent according to claim 1 , wherein the iron suboxide is at least one iron suboxide selected from the group consisting of magnetite, hyper-reduced magnetite and berthollide.

3. A process for producing an organic compound decomposing agent according to claim 1 , wherein the mixing ratio of the ion and the iron suboxide is in the range of 0.02:1-9:1 in weight ratio.

4. A method for decomposing organic compounds which comprises:

producing an organic compound decomposing agent by the process of claim 1 , and

introducing the organic compound decomposing agent into soil to decompose the organic compounds in the soil.

5. A method for decomposing organic compounds which comprises:

producing an organic compound decomposing agent by the process of claim 1 ,

introducing the organic decomposing agent into water to decompose the organic compounds in the water, and

separating the organic compound decomposing agent by solid-liquid separation.
