Аннотация

Voltammetric characteristics of vanillin are determined using electrodes modified with tin dioxide nanoparticles dispersed in surfactants of various nature in the Britton–Robinson buffer solution. The best characteristics are observed for a glassy carbon electrode modified by a dispersion of SnO2 nanoparticles in cationic cetylpyridinium bromide (SnO2–CPB/GCE). The electrode is characterized by cyclic voltammetry and electrochemical impedance spectroscopy. The electrooxidation of vanillin proceeds irreversibly with the participation of two electrons and two protons and is controlled by the diffusion of the analyte. A sensor based on a SnO2–CPB/GCE was developed to determine vanillin; it functions under conditions of differential pulse voltammetry. The analytical ranges for vanillin are 0.10–100 and 100–500 ?M with the limits of detection and quantification 20 and 67 nM, respectively. The sensor is selective to vanillin in the presence of saccharides, ascorbic acid and other phenolics.
