Batch sorption experiments were carried out using jackfruit leaf powder (JLP), for the removal of methylene blue (MB) from aqueous solutions. Effects of process parameters pH, adsorbent mass, concentration and contact time were studied. The amount of MB adsorbed per unit weight of the adsorbent increased with the increase of pH, concentration and contact time. The pH at the point of zero charge (pH(PZC)) of the adsorbent was found to be 3.9. Adsorption of M B was found highly pH dependent. The FTIR of the adsorbent was done to find the potential adsorption sites for interaction with the cationic MB dye. Equilibrium data were fitted to Langmuir and Freundlich isotherms. The equilibrium data were best represented by both the isotherms. Maximum dye uptake was found to be 326.32 mg/g, indicating that JLP call be used as ail excellent low-cost adsorbent for removal of MB dye. From experimental data it was found that adsorption of MB onto JLP followed Pseudo second order kinetics. The desorption studies showed that most of the MB call be recovered by decreasing the pH of the solution. The experimental result inferred that electrostatic attraction between the surface and the dye is one of the major adsorption mechanisms for binding MB to JLP surface.
