VAZQUEZ, M.V.; HERNANDEZ-LUIS, F.; LEMUS, M.  and  ARBELO, C.D.. Integral Analysis of the Process of Electro-Remediation of Andisols Polluted by Heavy Metals. Port. Electrochim. Acta [online]. 2004, vol.22, n.4, pp.387-398. ISSN 0872-1904.

An integral analysis was carried out on the results obtained in laboratory experiments on electro-remediation of soils using two heavy metal-contaminated volcanic soils from the region of Antioquia, Colombia. Measurements of pH, conductivity, and pollutant concentration were made on each soil. The results were related to the structural characteristics of the soils employed in the experiments. Under the present experimental conditions it was shown that the soil with the lower concentration of organic matter had a lower pH regulatory capacity, that treatment without using wash solutions was more efficient for the mobilization of the metals, and that the particular characteristics of each soil conditioned the efficiency of the treatment.

Keywords : andisols; soil pollution; electro-remediation; heavy metals; regulatory capacity.
