Description
Summary:This paper aims to evaluate the electrokinetic technique for remediation of mercury contaminated soils from the mine El Alacran, located in the San Jorge river basin from Colombian's Cordoba department. KI and NaCl solutions were used as complexing agents for removing mercury at two concentrations 0.01 M and 0.05 M, by applying voltages of 30 and 40 V, respectively. The best results were obtained when KI was used as complexing agent, reaching percentages of recovery up to 98.7%. In all experiments, the mercury moved towards the anode due to the complexation of anionic nature complex and was observed that increasing concentrations and voltages a more efficient and speedy removal of mercury in the soil was achieved. The results showed that the iodide has properties that make it a promising electrolyte solution for the removal of mercury in the soil.
