Sažetak
The review highlights the electroanalytical methods used for the determination of the artificial dye Sunset Yellow, one of the most frequently used azo–dyes, with a very wide field of the application during the last two decades. As azo–dyes may have detrimental effects on living organisms, their content in food must be strictly controlled. 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 – e.g., less time for sample preparation and determination, low investment and running cost, electrode miniaturization and modifications, as well as use of eco–friendly materials. This critical review focuses on the electrode materials and their modifications since they are the deciding factor for a successful voltammetric determination of Sunset Yellow. In addition to this, the reaction mechanisms for determination and analytical performance are also presented in the paper.
