| Abstract: | In this paper, the preparations and voltammetric characteristics of chitosan-modified glassy carbon (Ct-MGC) and platinum
electrodes are studied. Ct-MGC can be used for pre-concentration and quantification of trace amounts of platinum in solution.
At low pH medium, the complex of Pt with protonated group-NH3+ in the chitosan molecule has been confirmed by FT-IR spectra studies. |
