Electrodialytic remediation of soil polluted with heavy metals - Key parameters for optimization of the process

In this paper, the importance of some parameters for the efficiency of elec trodialytic soil remediation are evaluated. The parameters investigated are pH, the limiting current density and the addition of desorbing agents to t he soil. These three parameters are found to be of the greatest importance. Results show that electrodialytic soil remediation can be optimized by und erstanding and adjusting these parameters. For scaling up the remediation m ethod, these parameters are of crucial importance.
