Abstract

Uric acid shows good quality sensitivity with sodium molybdate and methyl red personalized glassy carbon electrode. In this amend sodium molybdate was ionically deposited resting on the surface of the working electrode of the glassy carbon electrode, and then the facade of the electrode was electropolymerized with methyl red. The electropolymerization of methyl red on the working electrode was done by potential cycling in 0.2M phosphate buffer solution at pH 5.0 to 8.0. Very sensitive peak potentials of uric acid pragmatic in the presence of two made-to-order materials. This sensitivity nature was precisely investigated at physiological pH of 7.4, the rate of scan consequence tells regarding circulation inhibited electrode assets and concentration effect gives for uric acid good limit of detection that is 3.020 x 10-5 M calculated at the modified electrode. The complete study explains the oxidation mechanism of uric acid concerning an identical number of electrons and protons on the surface of the Sodium Molybdate/Poly (Methyl Red) modified glassy carbon electrode with elevated sensitivity.
