%X Electrokinetic (EK) remediation coupled with activated carbon barrier was evaluated to remove nickel (500 mg/kg) from kaolinite. Laboratory experiments were performed by applying a constant voltage to create electric field strength of 1 or 1.25 V/cm for 3 days. Findings showed that the barrier filled with activated carbon could prevent the formation of reverse electro-osmotic flow, which had an adverse effect on the Ni(II) removal. Application of activated carbon barrier into EK process resulted in an increase of Ni migration from 11 to 47%.
