Bibliographic description in the original language

Ziyatdinova G. Electrooxidation of morin on glassy carbon electrode modified by carboxylated single-walled carbon nanotubes and surfactants / G. Ziyatdinova, E. Ziganshina, H. Budnikov // Electrochim. Acta. - 2014. - V.145. - P.209-216.

Annotation

Voltammetric characteristics of morin on glassy carbon electrode (GCE) modified by carboxylated single-walled carbon nanotubes (SWNT-COOH) and surfactants in phosphate buffer have been found. Cationic cetylpyridium bromide (CPB), nonionic Triton X100 and anionic sodium dodecylsulfate surfactants under different concentrations have been tested as modifier of SWNT-COOH/GCE. The form of CVs and oxidation potentials are not changed significantly in the presence of all type surfactants on the electrode surface that confirms negligible influence of surfactant on electron transfer rate. Morin oxidation currents are increased on surfactant-modified electrodes. The best characteristics are observed on CPB/SWNT-COOH/GCE when 1.8-fold increase of oxidation currents has been observed in comparison with SWNT-COOH/GCE. Mechanism of morin oxidation on CPB/SWNT-COOH/GCE is suggested on the basis of relationship between oxidation potential and pH of supporting electrolyte.
