| description | The present work is a contribution to copper removal study by adsorption on Double-Layered Hydroxides Co-Cr-HDL prepared by co-precipitation method at pH of 10. Characterization of the solid was performed by both FTIR and DRX techniques. The kinetic study and the determination of adsorption isotherms were carried out in a batch system at room temperature to evaluate the effect of the adsorbent-adsorbate contact time, the adsorbate initial concentration, the solution pH and the adsorbent mass on the retention of copper and the adsorption capacity of the synthesized HDL. Retention of copper reached 50 % on 0.05 g of HDL during 6 hours of contact at the pH of synthesized aqueous solution. Experimental kinetic data have been well described by the pseudo-second-order model and adsorption equilibrium can be represented by the Langmuir model which gives us information on the nature and the texture of the solid surface which would be homogeneous, with sites energetically identical, able to receive the copper ions in monolayer, without interaction between the adsorbed chemical species. |
