Ziyatdinova, G.K. Voltammetric determination of tartrazine on an electrode modified with cerium dioxide nanoparticles and cetyltriphenylphosphonium bromide / G.K. Ziyatdinova, H.C. Budnikov // J. Anal. Chem. – 2022. – V. 77. – № 6. – P. 664-670. |
| Аннотация |
We created glassy carbon electrodes (GCEs) modified with CeO2 nanoparticles and various surfactants and determined the voltammetric characteristics of tartrazine oxidation on them. The electrode modified with the cationic surfactant cetyltriphenylphosphonium bromide (CTPPB) ensures a 72.5-fold increase in the oxidation currents of tartrazine compared to a GCE. The oxidation of tartrazine on the CeO2-CTPPB/GCE proceeds irreversibly, involves one electron, and is controlled by surface processes. A procedure was developed for the voltammetric determination of tartrazine on a CeO2-CTPPB/GCE. The analytical range is 1.00–250 ?M of tartrazine with a limit of detection of 0.4 ?M. The procedure was applied to quantify tartrazine in the Tarkhun beverage. |
