Description
Summary:The aim of this study was to use a voltage difference to increase the bioavailability of hydrocarbons presents in the bottom sediments of oil tank. This experiment was carried out in a glass cuba with three compartment communicated by phosphate-buffered saline bridges that allowed the voltage difference and maintained the soil pH at optimum values for bacterial life. After several 4 days the bioavailability of hydrocarbon was increased by 18.8% in the area near the anode and 5.5% in the area near the cathode. El objetivo de este estudio fue utilizar una diferencia de voltaje para aumentar la biodisponibilidad de los hidrocarburos presentes en los sedimentos del fondo de tanques petroleros. El experimento se realizó en una cuba de vidrio con tres compartimento comunicadas por puentes salinos de buffer fosfato que permitieron la diferencia de voltaje y mantener el pH del suelo en valores óptimos para la vida bacteriana. Después de 4 días se aumento en un 18.8% los hidrocarburos biodisponibles en la zona cercana al ánodo y 5.5% en la zona cercana al cátodo.
