Abstract

In this study, a stabilization method was applied to stabilize heavy metals in soils collected from a domestic contaminated area and a Canadian mine site. The stabilizing agent used in the experiment was a solidifying agent developed by KERT Co., Ltd., Korea. The agent was applied to the samples at varying weight ratios of 0, 2, 5, 7, and 10% (w/w). and the concentrations of heavy metals in the effluent were monitored at predetemined time intervals. The results indicated that the stabilization efficiency of heavy metals (Cd, Cu, Pb) increased proportionally until the agent was increased to 5%, which showed almost no leaching of heavy metals after 28 days after agent application. Therefore, addition of 5% relative to soil mass was proposed to be the optimum dose for the stabilization agent.
