Abstract
The adsorption rate constant and capacities for the removal of Pb(II) from synthetic wastewater using chitosan silica were investigated. The adsorption kinetics model is used to determine the rate of adsorption is the order of the one nearing equilibrium and pseudo second-order. The results showed that the metal ion adsorption of Pb(II) reaches equilibrium at the 60 minute interaction by chitosan-silica bead. Adsorption kinetics model that is suitable for both the pseudo second-order rate constants. The adsorption followed the Langmuir and Freundlich isotherms but could best be approximated with the Langmuir model.
