Equilibrium and Kinetics Studies of adsorption of Copper (II) Ions on Natural Biosorbent

Rania Farouq and N. S. Yousef
Abstract—The Biosorption of Copper (II) ions from aqueous solution on natural biosorbent (Mussels) has been investigated. Batch shaking adsorption experiments were performed and equilibrium and kinetic isotherms were tested. Results show that Chitin can remove Copper (II) effectively from aqueous solution. To predict the adsorption isotherms and to determine the characteristic parameters for process design, eight isotherm models: Langmuir, Freundlich, Elovich, Temkin, Fowler–Guggenheim, Jovanovic, Koble-Corrigan, and Hill were applied to experimental data. The equilibrium data were analyzed. The results reveal that the adsorption isotherm models fitted the data in the order: Jovanovic > Freundlich , Koble-Corrigan> Temkin> Fowler–Guggenheim> Elovich> Langmuir, Hill. Adsorption kinetic data were tested using pseudo-first order, pseudo-second order and Elovich model. The kinetics of the adsorption were found to fit the Elovich model.

Index Terms—Biosorption, chitin, copper (II), equilibrium and kinetic models.
