In this paper, Sugarcane leaves (SL) used for removal of Pb⁺² as a recent adsorbent. The  untreated and treated leave of sugarcane analyzed by instruments like; FT-IR, SEM and EDX investigation. The using different standard solutions and water samples containing Pb⁺² ions in uneven  preliminary conc., bed-height, pH and flow rate at room temperature. It is also found that the break point period decreases with rise in inlet adsorbate conc. as the binding positions become additional saturated in the column. The adsorption curve also indicates that the adsorption capacity rises with rise in bed-height. Experimental data indicate that SL has great affinity to Pb⁺² ion removal. The Yoon-Nelson (YN) method also gives the confirmation and good evidence of Pb⁺² ions onto the SL bio-adsorption. We proposed that the major adsorption mechanism of Pb⁺² ions through a specific ion-exchange mechanism, and morphological surface precipitation.
