Different electrochemical soil remediation methods have been developed and the present
paper deals with the electrodialytic soil remediation method (EDR) [3–5]. The principle
of EDR differs from other electrochemical soil remediation methods (ECR) in the use of
ion-exchange membranes. In a few ECR methods, the electrodes are placed directly in
the soil, but in most methods the electrodes are placed in electrolyte solutions [1,2,7,8].
In EDR, the separations between the soil and these electrolyte solutions are ion-exchange
membranes whereas in ECR the separations are chemically passive barriers. A schematic
presentation of a laboratory cell for EDR is shown in Fig. 1.
