ABSTRACT

Chelating polymers have been employed successfully in some areas, such as removal of harmful trace metal ions, because of the highly selective adsorptive for heavy metal ions. They have also been given much attention with respect to the recovery of the adsorbed metal ions [1, 2]. In other words, the utilization of cellulose materials in their as-received state is facing some problems, for application as valuable new materials, such as dissolution of cellulose and coloring, and lacks its microorganisms and ire-resistant behaviours. Cellulose-metal complexes have been used to initiate graft copolymerization onto cellulose [3, 4] and dissolution of cellulose [5]. Functionalization of cellulose by either esteriication or etheriication reactions requires one approach for enhancing its solubilization in organic or water and, moreover, motivates its applications [5]. Cellulose derivatives

can react with metal ions, such as alkaline earth elements and heavy metal ions.
