摘要： PROBLEM TO BE SOLVED: To decontaminate soil/ground water contaminated with an organochlorine compound with iron powder (including colloidal iron powder), and simultaneously to prevent degradation in the strength of the ground by work for purification.
SOLUTION: The decontaminating material for the soil contaminated with the organochlorine compound consists of powder or slurry formed by adding low-alkalinity cement of pH 11 to the iron powder (including colloidal iron powder). The decontaminating material may be prepared by adding aluminum powder to the above decontaminating material. Also the decontaminating material may be prepared by adding a thickening material slurry to the slurry prepared by adding water to the above decontaminating materials. The amount of the low-alkalinity cement is defined as 10 to 50 kg per ±1 m
3 soil. The size of the aluminum powder is defined as ≤200 μm, and the amount thereof to be added is set on 0.1 to 2 kg (more preferably 0.5 to 1 kg) per ±1 m
3 soil.
