Electrochemical Determination of Tyramine Using a Carbon Ionic Liquid Paste Electrode Modified with f-MWCNTs/Graphene Nanocomposite Film
This paper describes the development of a carbon paste electrode based on the butyl-3-methylimidazolium bis (trifluoromethylsulfonyl) imide ([bmim] NTF2) ionic liquid and its modification with functionalized multiwalled carbon nanotubes (f-MWCNTs) /graphene (GR) nanocomposite film. The f-MWCNTs-GR modified carbon ionic liquid paste electrode (CILPE) was utilized for electrochemical determination of tyramine using the square wave voltammetry technique. The prepared electrochemical sensor exhibited an excellent electrocatalytic behavior for oxidation of tyramine molecules in solutions compared to the carbon paste electrode. This behavior can be assigned to the synergistic effect of carbon nanotubes, graphen and ionic liquid. The oxidation peak currents of tyramine were linear in the concentration range of 1–1000 μM with a detection limit of 0.5 μM. The obtained experimental results showed that the f-MWCNTs-GR/CILPE has a good selectivity toward tyramine molecules in the presence of interfering specious and it can be used confidently for measurement the concentration of tyramine in food and biological samples.
期刊介绍：
Electrocatalysis is cross-disciplinary in nature, and attracts the interest of chemists, physicists, biochemists, surface and materials scientists, and engineers. Electrocatalysis provides the unique international forum solely dedicated to the exchange of novel ideas in electrocatalysis for academic, government, and industrial researchers. Quick publication of new results, concepts, and inventions made involving Electrocatalysis stimulates scientific discoveries and breakthroughs, promotes the scientific and engineering concepts that are critical to the development of novel electrochemical technologies.
Electrocatalysis publishes original submissions in the form of letters, research papers, review articles, book reviews, and educational papers. Letters are preliminary reports that communicate new and important findings. Regular research papers are complete reports of new results, and their analysis and discussion. Review articles critically and constructively examine development in areas of electrocatalysis that are of broad interest and importance. Educational papers discuss important concepts whose understanding is vital to advances in theoretical and experimental aspects of electrochemical reactions.
