Аннотация

Chemically modified electrodes based on polymer nanocoatings as sensitive layers are some of the intensively developed areas in modern electroanalysis. Electropolymerization of compounds containing phenolic fragments is a promising approach for electrode surface modification. Novel electrodes based on a combination of carbon nanotubes and electropolymerized ellagic acid or aluminon were developed for the direct quantification of flavanones (naringin and hesperidin)?the major flavonoids of Citrus fruits. The conditions of monomers' potentiodynamic electropolymerization were optimized. Electrode surfaces were characterized by scanning electron microscopy and electrochemical methods. A glassy carbon electrode (GCE) modified with multi-walled carbon nanotubes (MWCNTs) and poly(ellagic acid) allowed for the quantification of naringin in the ranges of 0.050?1.0 and 1.0?100 ?M with the detection and quantification limits of 14 and 47 nM, respectively. Simultaneous voltammetric quantification of naringin and hesperidin in the ranges of 0.10?2.5 and 2.5?25 ?M for both analytes with the detection limits of 20 nM and 29 nM for naringin and hesperidin, respectively, was achieved on GCE modified with polyaminobenzene sulfonic acid functionalized single-walled carbon nanotubes (f-SWCNTs) and polyaluminon. High selectivity of the electrodes' responses to flavanones in the presence of typical interferences and natural phenolics was confirmed. The approaches were successfully applied to Citrus juices.
