| Abstract: | The recent progress in adsorbents for metal ions based on chitosan and its derivates was summarized in this article. Crosslink and chemical modification of chitosan and its derivates was introduced with emphasis, as well as the adsorption of metal ions of the crosslinked resin. The common cross-linking agent included glutaraldehyde, formaldehyde, epoxy chloropropane and (poly)ethylene glycol bisglycidyl ether etc. The introduction of functional groups such as carboxymethyl and crown ether to chitosan was the common chemical modification means, especially the introduction of carboxymethyl. The synthesis of chitosan resins using metal ions as templates and snake-cage resins based on chitosan derivates was also summarized in this paper. |
