Electric remediation technology is to insert the electrode into the contaminated soil area and form an electric field by applying a weak current. The water or external fluid in the soil gap can be used as a medium. In the electric field, because of the effect of the electric potential gradient, the organic pollutants move along the direction of the fluid medium, so as to eliminate those pollutants.<br>The main electrodynamic phenomena involved in pollutant removal are: (1) electromigration (2) electrophoresis (3) electrodialysis.<br>
