摘要
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 addition of desorbing agents to the soil. These three parameters are found to be of the greatest importance. Results show that electrodialytic soil remediation can be optimized by understanding and adjusting these parameters. For scaling up the remediation method, these parameters are of crucial importance.
