Remediation agent for contaminated soil and method for the remediation of soil
First Claim
1. A remediation agent for contaminated soil, comprising a slurry of fine iron particles in which the fine iron particles in the form of spheres having an average particle size of less than 10 μ
- m are dispersed in water by bubbles formed on the periphery of the particles.

Abstract
A method for the remediation of contaminated soil directly and effectively removes the contaminants such as organic halides from the contaminated soil, using remediation agents for soil. In more detail, the agents include a slurry of fine iron particles in which the fine iron particles having average particle size less than 10 μm are dispersed in water; and an aqueous suspended liquid that contains fine iron particles having average particle size less of 1 to 200 μm and a hydrophilic binder; and these agents are employable for the method for the remediation of contaminated soil.

11. A remediation agent for contaminated soil, comprising a slurry of fine iron particles in which the fine iron particles in the form of spheres having an average particle size of less than 10 μ
- m are dispersed in water, the fine iron particles being obtained by collecting a waste gas containing steelmaking dust produced from an oxygen-blowing converter for steelmaking during refining by wet dust collection, and then removing gas to obtain a slurry of the steelmaking dust.
