Abstract

The adsorption of Cd, Co, Pb and Zn by novel adsorbent polymer based on Lignin and Tannin was investigated. The adsorption of Cd, Co, Pb and Zn by prepared polymer was studied. Polymer was characterized using FTIR, UV, GC-Mass, X-ray spectra DSC and TG. All characterization techniques confirm the existence of Lignin and Tannin. Adsorption of Cd, Co, Pb and Zn ions by prepared polymer was investigated under different conditions. The effect of pH, Dose of polymer and agitation time was studied. The removal efficiency under different conditions was evaluated using atomic adsorption spectroscopy. To improve uptake and make in an industry workable process, this study suggests that modification of the native polymer would be required.
