Heavy metal removal from contaminated soils by electrokinetic process

Theoretical aspects of electrokinetic soil remediation for removal of heavy metals were described. More than 90% removal was achieved by electrokinetic remediation process where migration of contaminants in an imposed electric field occurred through the process of electroosmosis, electromigration and electrophoresis. The success of the process depends upon the specific conditions at the site that include type and amount of contaminant, soil type, pH and organic content of the soil.
