In current study the carbon-paste electrode modified by silica with embedded cetylpyridinium chloride for determination of Allura Red AC have been developed. The optimal conditions were determined to be for the square-wave voltammetric quantification: pH=2, Eads=300 mV, tads=300 s, amplitude – 40 mV, frequency – 25 Hz and potential scan rate is 250 mV sec-1. The calibration plot has linearity in the concentration ranges 0.04-0.2μM and 0.2-1.00μM. The LOD and LOQ are equal to 0.005μM and 0.015μM resp. The crafted sensor has been applied successfully to model solutions and in jelly candies anal. with RSD no more than 10%.
