Abstract
In this study, we successfully crosslinked chitosan using STPP and produced chitosan beads to adsorb copper ions and subsequently phosphate ions from aqueous solutions. The optimal concentrations of chitosan (2% w/v) and STPP (7.5% w/v) during chitosan beads preparation and the optimal pH of 5.0 during adsorption were determined. Several adsorption models, including pseudo-first-order, pseudo-second-order, Langmuir, and Freundlich models, were used to evaluate the static adsorption experimental data. Moreover, the chitosan beads were applied in a dynamic adsorption column and several models including Bohart-Adam, Thomas, Yoon-Nelson, and Clark models were used to describe the system. This study showed that after adsorbing heavy metal ions, chitosan-STPP beads can be used for further adsorption of toxic anions from wastewater.
