Аннотация

A voltammetric sensor based on a glassy carbon electrode with a layer-by-layer combination of carboxylated multi-walled carbon nanotubes and electropolymerized pyrogallol red has been developed for the determination of eugenol in essential oils. Conditions for obtaining a poly(pyrogallol red) film in potentiodynamic mode in a neutral medium were optimized to provide the best voltammetric response of eugenol. The electrode was characterized using scanning electron microscopy and a set of electrochemical methods. A significant improvement in the voltammetric characteristics of eugenol on the polymer-modified electrode was shown. The electrooxidation parameters of eugenol were calculated, and it was shown that the reaction proceeded with the formation of o-quinone. Under conditions of differential pulse voltammetry in a Britton–Robinson buffer with pH 2.0, the analytical range of eugenol was 0.75−100 μM with a detection limit of 0.73 μM. High selectivity for the determination of eugenol in the presence of inorganic ions and typical phenolic and terpene components of essential oils has been shown. This approach was successfully tested with eugenol-containing essential oils and compared with an independent method.
