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.
