    摘要: A method for insolubilizing and stabilizing a heavy metal contained in a waste, which comprises melt-kneading the waste (A) containing a heavy metal together with an alkali metal compound or alkaline earth metal compound (B) and either sulfur (C) or a sulfide (D) optionally further with a metal salt (E) which has a higher standard electrode potential than those of cations of ingredient (B) or (E) in the presence of a nonaqueous medium, and then cooling the melt to solidify it. Thus, the heavy metal contained in the waste can be efficiently immobilized and prevented from dissolving out.
