Voltammetric Determination of Vitamin B6 Using a Modified Gold Electrode
Russian Journal of Physical Chemistry A. 2024. Vol. 98. No. 6. P. 1318–1321.
The electrochemical properties of vitamin B6 have been studied. Its analytical signal was obtained using a gold electrode modified with cobalt(II) tetra-4-sulfophthalocyaninate. The optimum experimental conditions were determined. A technique for immobilizing the modifier on the surface of the gold electrode is proposed. The mechanism of vitamin B6 oxidation on the electrode was examined.
