ABSTRACT:
To decontaminate soil, a generally thin porous medium is used. A cathode is applied to one face of the porous medium and an anode is spaced apart from the other face of that porous medium to define a generally thin spacing for receiving a generally thin layer of soil to be decontaminated. An electric potential is applied to the first and second electrodes in view of transferring the contaminants from the thin layer of soil to the porous medium. A porous membrane may be positioned between the thin layer of soil and the anode. The system may be of the conveyor type to enable displacement of the porous medium, the porous membrane, and the layer of soil between the anode and the cathode. Also, the system may comprises a series of at least two pairs of anode and cathode supplied with electric potentials of different amplitudes.
