Abstract
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.
