In the Summer 2004 issue of Remediation, the authors presented a study of the influence of buffering behavior in contaminated Andisol soil. This article, Part II, expands on this research by presenting the results of laboratory tests conducted to study the movement of heavy metals in contaminated Andisol soil during the first stage of an electrochemical remediation process. The analysis was performed on the soil after treatment and also on the washing solutions collected during the first four hours. In order to analyze the effectiveness of fast and simple techniques for monitoring the electroremediation process, computer-aided modeling of speciation in the soil solution was performed in connection with the remediation treatment. The results show that the metals moved mainly as positive species in the soil and later occurred as insoluble forms relative to the pH value in the washing solution from the cathode chamber. © 2005 Wiley Periodicals, Inc.
