In this study, a combined continuous flow system was designed to remove Pb and Cd from heavily contaminated mine tailing soils. 0.05 M Na(2)EDTA was used as a chelating agent to remove Pb and Cd from polluted soil, taken from the vicinity of Kayseri CINKUR, Turkey. The initial concentrations of Pb and Cd were 16381 +/- 643 and 34347 +/- 1310 mg kg(-1), respectively. The electrochemical treatment process was applied to the waste washing solution, which emerged after being extracted from soil column and contained Pb and Cd. Metal ions were transformed to the metallic form by applying the electrochemical treatment process to the washing solution, containing Pb2+ and Cd2+.
