Abstract: The use of permeable adsorbing barriers to protect groundwater from heavy metals pollution has been experimentally studied. Hexavalent chromium adsorption isotherms were measured for two adsorbing media under various conditions. Adsorbing results were modeled by considering competitive pseudo-reaction between cations and anions present in solution and the activated sites distributed over the adsorbing surface. An example of effectiveness of permeable adsorbing barrier is eventually given, for a very simple one dimensional case study. To this aim, mathematical modeling of groundwater flow and conservative solutes transport in presence of adsorbing materials is briefly discussed.
