초록

Soils collected from an agricultural field in Youngdong, Chungbuk province were intentionally: contaminated with lead and copper. The efficiencies of soil washing with HCl, SDS and Tween 80 were investigated through the column mode experiments. Washing with 0.1 N HCl obtained the best result for lead and copper removal (95.04 %, 95.94 %). In case of SDS, lead and copper removal rate was such poor as 7.1 % and copper was 24.04 %, respectively. Meanwhile, washing of contaminated soil with Tween 80, did not show any significant removal effect. It was found that the washing efficiency was dependent on pH of washing agent.
