Adsorption Kinetics of Pb (II) and Two-Stage Batch Sorption Design for Removal of Lead (II) from Aqueous Solution by Modified Sugarcane Bagasse

This paper reports an enhancement of Pb(II) ion adsorption capacity onto sugarcane bagasse (SB) material via grafting acrylic acid on its surface with assistance of the cold plasma. The adsorption data were found to be consistent with the pseudo-second-order model. The two-stage batch sorption design of the sorption of lead ions onto ASB been applied based on the pseudo-second-order model to predict the minimum operating time for at each appropriate adsorption efficiency of Pb(II) removal from aqueous solution.
