Activated carbons were prepared from chips of Labill, as by chemical activation using phosphoric acid activating agent. The influence of activation parameters was studied on the adsorption of lead: impregnation ratio (activating agent (g)/precursor (g)) and activation temperature. The materials obtained were characterized by N2 adsorption at -196 °C, SEM and FTIR. The parameters affecting the adsorption process of lead was studied: contact time, ratio mass carbon/volume of solution, temperature and pH, obtained adsorption capacities of up to 142,1mgPb / g.Achieved 99,9% removal of lead on industrial effluent.

Se prepararon carbones activados a partir de astillas de eucalipto ( Labill), mediante activacion quimica usando como agente activante al acido fosforico. Se estudio la influencia de los siguientes parametros de activacion sobre la adsorcion de plomo: razon de impregnacion (agente activante(g)/precursor(g)) y temperatura de activacion. Los materiales obtenidos se caracterizaron mediante adsorcion de N2 a -196 °C, SEM y FTIR. Se estudiaron los parametros que afectan el proceso de adsorcion de plomo: tiempo de contacto, razon masa de carbon/volumen de la solucion, temperatura y pH, lograndose obtener capacidades de adsorcion de hasta 142,1 mg Pb/g. Se logro remover el 99,9% del plomo contenido en un efluente industrial.
