A selective chitosan adsorbent may remove Cd 2+ and Pb 2+ ions in aquatic environment to reduce pollution. This study has applied crosslink chitosan to reduce Cd 2+ and Pb 2+ ions in water. The study is related to the searching of optimum condition with respect to citric acid and sodium tripolyphosphate concentrations in a batch method. The study also includes the determination of optimum pH and interaction study of complex molecule with either Cd 2+ or Pb 2+ ions in relation to competitive chitosan adsorption. The optimum pH is found at pH 5. The optimum concentration of citric acid with chitosan is found to be 1% (b / v). It is concluded that chitosan adsorbent is selective for Pb 2+ over Cd 2+ ions.
