Adsorption of Copper (II) from Aqueous Solutions on Antimony Pillar/Clay Composite

H. Cherifi, S. Bougherara, K. Louhab


Abstract: The separation of copper from aqueous systems is studied for environmental protection. In this paper was studied the elimination of cooper from dilute aqueous solution by adsorption on a crude and chemical modified clays (pillared layers clays).The kinetics study of the adsorption of copper on the modified clay showed that equilibrium is reached after 60 mn. A high adsorption performance was recorded for the following optimum conditions at the temperature T = 25°C and the solid/liquid ratio = 2, Initial concentration of ion Cu2+ =40 mg /L, the amount of adsorbent clay = 800 mg, pH = 6.
