THE MAIN purpose of this work is to remove lead ions from aqueous solution by using carbon of red beet roots (CRBR). The influence of contact time, initial concentration, temperature, pH of solution and the dose of adsorbent were studied. It was found that the maximum removal percentage of Pb(II) has reached 99.99% at room temperature by applying the following conditions: adsorbent loading weight 0.1 g, contact time 24 hrs, and 9.993 m.mol/L concentration of lead ions. The adsorption process of Pb(II) on CRBR was of chemical nature and followed the kinetic formula of pseudo second –order reaction. Results of FTIR spectroscopy and scanning electron microscopy made it possible to propose mechanism for the adsorption process. The recovery of the adsorbed Pb(II) ions on CRBR surface was done by using 1 N acetic acid solution resulting a recovery of 87.466%.
