Abstract
The characteristics of electroosmosis drainage in clayey soil were investigated, when an electrokinetic technique was applied for the purpose of separating heavy metals in contaminated ground. A series of laboratory tests, considering voltage, zeta potential, pH distribution, and current, were performed for a lead-contaminated kaolin. The results of laboratory tests were compared with numerical analysis of finite difference method. The 1311owing conclusions were obtained: The flow velocity in electroosmosis was very sensitive to the chemical and electrical characteristics of the clay. As the concentration of ion increases, the flow rate decreases and the amount of drainage also decreases as time elapses.
