Studies on Electrokinetic Remediation of Radioactively Contaminated Soil By Using Sulfuric Acid

Won-Zin Oh, Gye-Nam Kim


H2SO4 and citric acid were used as additives for the electrokinetic remediation experiment to increase removal efficiency of Cs and Co from the radioactive soil waste stored for more than 10 years. The average effluent velocity discharged from the elctrokinectic remediation experimental column was 2.010 cm/min and the discharged soil wastewater volume for 10 days is 3.6 pore volume of the column. 97% of Co in the column was decontaminated for 10 days of operation, while only 54% of Cs was decontaminated. These results are considered that the absorption equilibrium coefficient of Cs is higher than that of Co. The predicted values of the residual concentration by the proposed mathematical model were well coincided with the experimental results within the experimental error range
