The powdered seeds of Adenanthera pavonina are used to study the biosorption of Cu(II) from aqueous solution. The batch experiments are conducted at at different initial concentrations (10-70 mg/L) of Cu(II) over a contact period of 5-60 minutes. The biosorption equilibrium is established by 40 minutes. The pseudo-first order, the pseudo-second order, Elovich and intra-particle diffusion models have been analyzed to understand the kinetics of the biosorption process. The pseudo-second order kinetic model is found to be the best fit for the present experimental data. The maximum heavy metal ions adsorbed is found to be 10.917mg/g. The present study shows that the powdered Adenanthera pavonina seeds are efficient in biosorption of Cu(II) ions from aqueous solutions.
