This research investigates the effect of ionic charge and size on the mobility of specific metal ionic species in sandy soil under an electric field. During Phase-I experiments, three ions: lithium, lead and, aluminum were initially selected for study. Since the resistance of the cell varied with time, power could not be maintained constant. Therefore, a numerical integration technique was adopted to compare the results. These results show that the mobility of the ions increased with the increase in valence of the ions (for lithium and lead). However, aluminum interacted with and adsorbed to sand. To overcome this problem, aluminum spiked sand was used for Phase-II testing. During this phase, lithium, lead, and yttrium ions were evaluated. These results suggest that the mobility of the ions increased with increase in valence of the ions (Y > Pb >Li). However, ionic size did not have a substantial effect on the ionic movement.
