Аннотация

Hydroxycinnamic acids are one of the most widely distributed classes of natural phenolics in plants. Their coexistence requires selective methods for quantification. Voltammetry on chemically modified electrodes is one of the approaches to solving this problem. Electrodes based on electropolymerized triphenylmethane dyes give sensitive and selective responses to natural phenolic antioxidants of different classes. In this work, a combination of polyaminobenzene sulfonic acid functionalized single-walled carbon nanotubes (f-SWCNTs), and poly(phenol red) was used as an electrode surface modifier. The polymeric coverage was obtained by potentiodynamic electropolymerization, the conditions of which were optimized on the basis of the voltammetric response of the hydroxycinnamic acid mixture. Poly(phenol red)-based electrodes provided well-resolved peaks of caffeic, ferulic, and p-coumaric acids, and a significant increase in the oxidation currents compared to bare glassy carbon (GCE) and f-SWCNTs-modified electrodes. Simultaneous voltammetric quantification of caffeic, ferulic, and p-coumaric acids was performed for the first time. Two linear dynamic ranges of 0.10?2.5 ?M for all acids, 2.5?100 ?M for caffeic acid, and 2.5?50 ?M for ferulic and p-coumaric acids were achieved using differential pulse voltammetry in a Britton?Robinson buffer with a pH of 2.0. The limits of detection were 47.6, 22.4, and 38.0 nM for the caffeic, ferulic, and p-coumaric acids, respectively.
