Adsorption studies of lead (II) and nickel (II) ions on chitosan-G-polyacrylonitrile

Author(s): Shanmugapriya A, Hemalatha M, Scholastica B and Augustine Arul Prasad T

In the present work, graft copolymerization of polyacrylonitrile onto chitosan has been carried out in the presence of ceric ammonium nitrate redox initiator. Chitosan has been used as an adsorbent for the removal of heavy metal ions from aqueous solution through adsorption process. The property of chitosan is enhanced by grafting. The prepared copolymer was characterized by FTIR, XRD, TGA and SEM. The effect of pH, contact time and amount of adsorbent dose were also investigated. The experimental data were fitted to Freundlich and Langmuir adsorption isotherms.
