A KINETIC STUDY OF CU (II) BIOSORPTION ON TO THE LEAVES OF CITRUS AURENTIFOLIA

*Dr. Naveen Chandra Joshi and Dr. Vijay Kumar Chhibber

ABSTRACT

The present study deals with the adsorption of copper (II) ion on to the leaves of Citrus aurentifolia as low cost adsorbent. The adsorption process of copper (II) ion was carried out under batch operation. The equilibrium data of adsorption have been tested with different kinetic parameters such as Langergren’s first order, pseudo second order, elovich kinetic model and intra particle diffusion. All the parameters of kinetic model were evaluated and indicate the suitability of adsorption of copper onto adsorbent.
