    Abstract

    In this paper, the importance of some parameters for the efficiency of electrodialytic soil remediation are evaluated. The parameters investigated are pH, the limiting current density and the adding of desorbing agents to the soil. Three parameters are found to be of greatest importance. Results show that the electrodialytic soil remediation can be optimized by understanding and adjusting of these parameters. For scaling up of the remediation method these parameters are of crucial importance.
