Abstract
In this study, fabrication of carbon paste electrode amplified with CdO/CNTs nanocomposite and 1-ethyl-3-methylimidazolium tetrafluoroborate (CdO/CNTs/1-E-3-MITFBr/CPE) for determination of carmoisine was investigated. The electro-oxidation of carmoisine occurs at a potential about 680 mV at a surface of CdO/CNTs/1-E-3-MITFBr/CPE and this mount is less positive than the bare carbon paste electrode at the optimized condition. The square wave voltammograms (SWV) peak currents of carmoisine show good linear dynamic range (0.1-700 μM) with a detection limit of 40.0 nM. Finally, the CdO/CNTs/1-E-3-MITFBr/CPE was used as highly selective sensor for determination of carmoisine in real samples.
