The adsorptive capacities of active carbons are essentially attributed to the internal surface area, porosity and surface reactivity. We described in this work chars obtained in one step in a rotary klin starting from two different lignites. In order to improve their adsorption capacities, a mild oxidation is proposed and evaluated. The objective of this work is to explore the feasibility of the use chars for adsorption in liquid and gaseous phases. The physical and the chemical effects of the oxidative treatment are discussed and connected to the modification of their adsorptive properties.
