Özet
New crosslinked derivative of chitosan was prepared by the condensation reaction ofchitosan (CS) and dichloro glyoxime. Structural analysis of chitosan derivative (CSL)was performed by elemental analysis (C, H, N), SEM measurements, FT-IR, solid-state13C CP/MAS NMR, XRD-powder and TGA. Crosslinking ratio was determined from theelemental analysis by using the C/N and found to be 70%. The swelling behavior ofderivative was investigated on pH 3-7 and 10 at 25 and 37°C. Metal ion uptake capacity wasstudied 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 retentioncapacity and metal uptake capacity of new cross-linked chitosan derivative is higher thanchitosan and metal uptake sequence are Cu(II) > Fe(II) >Cd(II) > Co(II) > Ni(II)respectively.
