Abstract
For the reservoir sediment highly contaminated with total Cr, Pb, and Cd, the applicability of electrokinetic remediation method was evaluated. Also, BCR sequential extraction method was adopted to compare the heavy metal speciation in between before and after electrokinetic reaction that is operated under constant current condition for the sediment. After reaction, total Cr and Pb moved toward the direction of anode, while Cd tended to cathode and stayed highest in the midst of sediment specimen. From the BCR sequential extraction analysis, it was known that for total Cr and Pb the residual fraction that showed high fraction before reaction decreased and changed to the oxidation fraction. On the other hand, for Cd the fraction of exchangeable/carbonate that dominated most fractions before reaction changed to the residual and oxidation fractions.
