| description | The electrochemical behavior of pyridoxine was studied in 0.1 mol × L<sup>−1</sup> NaX (X = F, Cl, Br) support electrolyte on a gold electrode using cyclic voltammetry and UV–Vis spectrophotometry. The influence of gold nanoparticles (AuNPs) on the electrochemical behavior of pyridoxine was studied. The experimental results obtained by both cyclic voltammetry and UV–Vis spectrophotometry indicate strong interactions in the B<sub>6</sub> and NaBr/NaCl_AuNP systems, while in the NaF_B<sub>6</sub>_AuNP ternary system the results indicate a mechanism of direct electrochemical degradation of vitamin B<sub>6</sub>. The experimental results obtained for the electrochemical degradation of pyridoxine, in the presence of chloride and bromide ions, indicate strong interactions in the NaCl_B<sub>6</sub>_AuNP and NaBr_B<sub>6</sub>_AuNP systems associated with the spectrophotometric identification of the electrogenerated intermediates, while in the presence of fluoride ions no such products are identified. The development of the mechanism of electrochemical degradation of the pyridoxine molecule predicts both the formation of the corresponding electrogenerated intermediates and the steps of electro-incineration in a direct mechanism. |
