Abstract :

The series of batch laboratory experiment were carried out by using activated Glossocardia linearifolia Stem (AGLS) for the removal of copper (II) ions from aqueous solution by the adsorption process. The investigation was carried out by studying the influence of initial pH, contact time, adsorbent dosage and initial concentration of copper. All batch experiments were carried out of constant temperature wrist – action shaker that operated at 200 rpm. The single component equiliium data was analyzed by Langmuir and Freundlich isotherms. Maximum adsorption of the copper ions, i.e. >90% has been achieved in aqueous solution using 0.025g of AGLS at a pH of 6.6. The kinetic process of copper AGLS was described by applying pseudo second order rate equation, Elovich model and intra– particles diffusion. The activated AGLS investigated in this study carries high potential for the removal of copper ions from aqueous solution. The various thermodynamic parameters like ∆GO, ∆HO, and ∆SO and were analyzed to observe the nature of adsorption.
