Abstract

Electrokinetic characteristic of natural soil dependent on flushing agents is studied to determine the best agent used in the hybrid electrokinetic remediation system. The soil containing 7.6% Fe$_2$O$_3$is spiked with lead. The flushing agents to be inject into anode are HCl, Acetic acid, Citric acid, EDTA and SDS. Test results showed that the early electrical potential of EDTA is lower than the value of the others. And the pH in anode reservoir is higher. Elcetrokinetic characteristic of all the sample except for EDTA is about the same.
