Sažetak
A possibility of using voltammetry at electrochemically activated glassy carbon electrode for the direct determination of artificial azo-dye, Sunset Yellow, is demonstrated. The Sunset Yellow, known also as E110, may have detrimental effects on living organisms. Thus, their content in food must be strictly controlled, especially in candies, beverages and soft drinks. Despite other analytical methods for determination of azo-dyes, the electroanalytical methods, especially voltammetric methods, offer many other advantages besides high sensitivity, selectivity and reproducibility. [1] The electrochemical behaviour of the Sunset Yellow is studied by cyclic voltammetry using the activated glassy carbon electrode. It is shown that the signal of electrochemical reduction and oxidation of Sunset Yellow is the most pronounced in a neutral medium at pH 7.0 in 0.1 mol dm - 3 KNO 3 . The dependence of the electrochemical current of the dye on its concentration (potential of – 0.688 V for reduction and 0.780 for oxidation of Sunset Yellow) is linear over a wide range (90 to 13500 mg/L with the determination limit 90.4 mg/L and detection limit 45.2 mg/L. A procedure for quantifying the dye in several food products and drinks is proposed. References: [1] Vladislavić, N. ; Buzuk, M. ; Škugor Rončević, I. Brinić, S.
