Electrochemical behaviour of platinum at polymer-modified glassy carbon electrodes

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.
