In this study, the adsorption behavior of a low-cost adsorbent, corn cob, with respect to Pb(II), Mn(II), Cd(II), Ni(II) and Co(II) ions, has been studied in order to consider its application to the purification of metal finishing processing industrial wastewater. The batch method was employed and parameters such as: Biosorbent dose (0.5, 1, 2, 3, 4 and 5 g/L), influence of pH were carried out between (3 and 8) finding the optimal operating pH was (6), contact time to achieve the equilibrium is found to be (3 hours) for Pb(II), Cd(II), Ni(II) and Co(II) ions and (4 hours) for Mn(II) ions. Adsorption parameters were determined using both Langmuir and Freundlich isotherms, the experimental data were better fitted to the Langmuir equation than to Freundlich equation. Corn cob showed a real solution to remove heavy metals from real wastewaters.
