Abstract:	The voltammetric behaviors of azo dyes on glassy carbon electrode were investigated in an aqueous containing various supporting electrolyte. The possible reaction mechanisms were discussed by the relations of scan rate and peak potentials and currents. The electroreduction process is applied for the quantitative determination of Lithol Rubine B azo dyes cosmetic products. Comparison with results obtained from high performance liquid chromatography shows good agreement.
