METHOD FOR REDUCING ELUTION OF FLUORINE FROM CONTAMINATED SOIL AND COMPOSITION AND KIT FOR REDUCING ELUTION OF FLUORINE FROM CONTAMINATED SOIL

摘要

PROBLEM TO BE SOLVED: To provide a method capable of reducing elution of fluorine from contaminated soil that requires no complex devices or complicated operations, the processing cost of which is low, which is capable of in situ processing, and which has no possibility of secondary contamination.;SOLUTION: The method for reducing elution of fluorine from contaminated soil includes a step of mixing contaminated soil contaminated with fluorine with a phosphate compound, a calcium compound, and a compound expressed by chemical formula (1): Ca_(7-1.5x)Fe_x(OH)_14/yH₂O (in chemical formula (1), 1.7≤x≤2.3, 1≤y≤6).;COPYRIGHT: (C)2012,JPO&INPIT
