Аннотация

Glassy carbon electrode (GCE) modified with carbon nanofibers (CNF) and surfactants has been tested for the determination of vanillin in Britton-Robinson buffer. Cationic cetylpyridium bromide (CPB), nonionic Triton X100 and anionic sodium dodecylsulfate surfactants under different concentrations have been tested as modifier of CNF/GCE. The best form of CVs and voltammetric characteristics of vanillin have been obtained on CPB(0.5 mmol dm-3)/CNF/GCE when the 1.4-fold increase of oxidation peak currents has been observed in comparison with CNF/GCE. The electrode has been characterized by scanning electron microscopy and electrochemical impedance spectroscopy (EIS). The EIS data indicate that CPB/CNF coverage significantly increases the charge transfer (Rct=0.24?0.04 kΩ vs. 4.6?0.1 kΩ for GCE). Mechanism of vanillin oxidation on CPB/CNF/GCE is suggested. The electrooxidation is diffusion-controlled irreversible process with participation of two electrons and two protons and formation of
