Removal of Pb(II) Metal Ions from AqueousSolutions Using Chitosan-Vanillin Derivativesof Chelating Polymers

Abstract

Our study investigates the removal of Pb(II) ions found in aqueous solutions using chitosan-vanillin polymeric material. The effects of pH, agitation time, adsorbent mass, and initial amount of studied ion on the chelation process have been carried out using batch experiments. The quantity of residual ions has been estimated via atomic absorption spectrometry. The polymers are characterized using infrared spectroscopy, TGA, SEM, and BET surface area.
