Abstract
The binding of heavy metal ions onto cross-linked chitosan in dilute aqueous solution has been investigatedas a function of pH (4.0 and 7.0), agitation period (10-180min) and concentration of various metal cations (5, 10, 50 and10ppm). In order to obtain adsorbents that are insoluble and stable, and prevent the dissolution loss of chitosan into anacidic aqueous solution, chitosan flakes were cross-linked with epichlorohydrine (ECH) and its adsorption behavior wascompared with that of the non cross-linked chitosan. An advantage of ECH is that it does not eliminate the cationic aminefunctional group of chitosan. In terms of adsorption ratio, the chitosan cross-linked at an ECH was inferior to original chi-tosan and was found that chitosan has a selectivity much remarkable than the cross-linked chitosan in low concentratedchitosan and the non cros-linked chitosan concerning the adsorption of Ni2+ , Co2+ , Pb2+ and Zn2+ acidic solution.
