SOIL TREATING MATERIAL AND SOIL DECONTAMINATING METHOD USING THE SAME |
摘要 |
<p><P>PROBLEM TO BE SOLVED: To provide a soil treating material which exhibits more excellent capacity for adsorbing fluorine when applied to fluorine-contaminated soil and from which the once adsorbed fluorine is restrained from being eluted again. <P>SOLUTION: The soil treating material for insolubilizing fluorine contains an iron oxide (1) having 100 m<SP>2</SP>/g specific surface area at the least and at least one aluminum compound (2) selected from aluminum hydroxide and a compound for producing aluminum hydroxide when hydrolyzed or neutralized. The soil decontaminating method comprises a step of adding the soil treating material to the fluorine-contaminated soil. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
