Batch Biosorption of Copper(II) by Sunflower Shell

Abstract:

In this manuscript, Cu (II) uptake by Sunflower Shell from aqueous solutions was investigated using batch biosorption techniques. The biosorption equilibrium studies were realized as a function of contact time, initial Cu (II) concentration, biosorbent dosage, pH, temperature, agitation rate and particle size. In addition, the mechanism of the Cu (II) removal was explained on the basis of the results of Fourier Transform Infrared (FTIR) spectroscopy. In order to gather information about the adsorption mechanism at various pHs, electrophoretic mobilites of particles were measured. The efficiency of Cu (II) ions uptake from aqueous solutions increased as pH, temperature and agitation rate of the solution increased, but decreased with the increase of biosorbent particle size.
