Özet
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.
