Item Efficacité des Argiles à Piliers d’oxydes d’Aluminium et de Fer pour l’élimination du Cu (II) à partir des Solutions Aqueuses(University of M’HAMED Bougara Boumerdes, 2015) Cherifi-Naci, H.; Boughrara, S.; Louhab, K.Pillared Clays with polycations of Aluminum and Iron have been synthesized from natural bentonite using the solutions of Al (NO3)3.9H2O and Fe (NO3) 3.9H2O as pillaring agents. The resulting pillared clays have been characterized by X-ray diffraction (XRD), X-ray fluorescence (XRF) and by infrared spectroscopy (FTIR) .The d-spacing of pillared clays of Aluminum and Iron is 20.25 A° and 30.23 A°, respectively. The specific surface area of the clay pillars of aluminum and iron is 290 and 360 m2 /g, respectively. The kinetic study of the adsorption of copper on the modified clays showed that equilibrium is reached after 60 min. A high adsorption performance was recorded for the following optimal conditions: at the temperature T = 25 ° C, the solid / liquid ratio = 2, the initial concentration of the ion Cu 2+ = 40 mg/l, the amount of adsorbent clay = 800 mg and pH = 6Item Adsorption of copper (ii) from aqueous solutions on antimony pillar/clay composite(Aljest, 2015) Cherifi, H .; Bougherara, S.; Louhab, K.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
