ABSTRACT: This study was carried out to investigate the effectiveness of electrokinetics to remediate soft kaolinite clay soils contaminated with copper and cadmium at concentration of 150 mg/kg. The tests were performed in four identical electrokinetic columns. An electric field intensity of 140 V/m was applied during 118 hr of remediation with the top electrode serving as the anode and the bottom electrode serving as the cathode. The results showed that electrokinetics was effective in removing water from the contaminated soil and the highest removed volume was 2070 ml compared to 693 ml in the control. Electrokinetic was effective in removing part of the heavy metals from most of the contaminated soil with the highest removal of 89% near the anode.
RÉSUMÉ: Cette étude a été réalisée pour étudier l'efficacité de l'électrocinétique pour assainir les sols mous argile kaolinite contaminée avec du cuivre et du cadmium à une concentration de 150 mg / kg. Les tests ont été effectués dans quatre colonnes identiques électrocinétique. Une intensité de champ électrique de 140 V / m a été appliqué au cours de 118 h de l'assainissement avec le haut électrode servant d'anode et le fond électrode servant de cathode. Les résultats montrent que électrocinétique a été efficace pour éliminer l'eau du sol contaminé et le volume le plus élevé a été supprimé 2070 ml contre 693 ml dans le contrôle. Électrocinétique a été efficace pour éliminer une partie des métaux lourds de la plupart des sols contaminés par le plus grand retrait de 89% près de l'anode. 1 INTRODUCTION
