Abstract :New crosslinked derivative of chitosan was prepared by the condensation reaction of chitosan CS and dichloro glyoxime. Structural analysis of chitosan derivative CSL was performed by elemental analysis C, H, N , SEM measurements, FT-IR, solid-state 13C CP/MAS NMR, XRD-powder and TGA. Crosslinking ratio was determined from the elemental analysis by using the C/N and found to be 70%. The swelling behavior of derivative was investigated on pH 3-7 and 10 at 25 and 37°C. Metal ion uptake capacity was studied towards of selected transition metals Cu II , Ni II , Co II , Fe II and Cd II cations in aqueous medium. According to the results of the analyses; water retention capacity and metal uptake capacity of new cross-linked chitosan derivative is higher than chitosan and metal uptake sequence are Cu II > Fe II >Cd II > Co II > Ni II respectively
