METHOD FOR IMMOBILIZING HEAVY METAL IN SOIL OR INCINERATION ASH USING PHOSPHATE COMPOUND AND METHOD OF TREATMENT OF SOIL OR INCINERATION ASH USING THE SAME

摘要

The present invention relates to a method for immobilizing heavy metals in soil or incineration ash using phosphate compounds and a method for treating soil or incineration ash using the same, and more specifically, to treating soil or incineration ash contaminated with heavy metals with an aqueous solution of phosphate having a pH of 3 to 8 Thus, the present invention relates to a method for immobilizing heavy metals in soil or incineration ashes simply and effectively without the need for additional post-treatment, and to a method of treating soil or incineration ashes using the same.;Phosphates, Soil, Incinerator, Heavy Metals, Immobilized, Treated
