The electrochemical behavior of ascorbic acid (AA) and uric acid (UA) in both aqueous cetylpyridinium bromide (CPB) and sodium dodecyl benzene sulfonate (SDBS) micellar solutions have been studied by cyclic voltammetry. The oxidation peak potentials shift more negatively, and the peak currents increase in aqueous CPB micellar solutions for AA and UA. However, the oxidation peak potentials shift more positively, and the peak currents decrease in aqueous SDBS micellar solutions for AA and UA. Therefore, CPB can enhance the electrochemical oxidation reaction for AA and UA, and SDBS hinders the electrochemical oxidation reaction. The electrochemical kinetic parameters for AA and UA in both aqueous CPB and SDBS micellar solutions are determined by chronocoulometry (CC) and chronoamperometry (CA). The charge transfer coefficients _ and the electrode reaction rate constants kf for AA and UA are enhanced in aqueous CPB micellar solutions, but reduced in aqueous SDBS micellar solutions. The pulse differential voltammetric behavior for AAand UAare also investigated in this work. The experimental results show that the oxidation peak potentials forAAandUAare separated by 270mVin the presence ofCPB in aqueous PBS (phosphate buffer solution, pH 6.8) solutions. Thus, AA and UA can be selectively determined in aqueous CPB micellar solutions, especially selectively determination of UA in the presence of excess of AA is possible. According to our work, the practical application of the results can be used to determineUAin human urine and serum samples, the determination results are satisfied.
