The adsorbent dose, contact time, initial metal ions concentration, temperature, pH were determined and adsorption isotherms were obtained for Mn (II) metal ions. Kinetic data reveals that adsorption mechanism follows pseudo second order model also fitted to Freundlich and Langmuir adsorption isotherms. The surface modified GAC were characterised by SEM-EDAX and FTIR technology. Copyright@ International Science Community Association
