چکیده
There have been increasing interests in finding new and innovative solution for removal of contaminants from soils recently. In the present investigation, electro kinetic (EK) process coupled with activated carbon barrier to remove Nickel from kaolinite clayey soil is investigated. Laboratory tests were performed by applying a constant voltage to nominal electric field strength of 1 and 1.25 V/cm with initial Ni concentration (500 mg/kg) for 3 and 7 days. Results revealed that, the coupled technology of EK with barrier when filled with activated carbon could effectively prevent the reverse electro osmotic flow which has adverse effect on the Ni removal from soil. In addition, 20-50% of Nickel migration towards the cathode during the tests was achieved.
