| Shrnutí: | Title screen This paper describes a simple colorimetric method for determination of Brilliant Blue, Sunset Yellow, Ponceau 4R and Tartrazine using transparent polymer optode. The method provided acceptable linear ranges 0.01-3.0 mg L−1 with correlation coefficients higher than 0.995 under the optimal conditions. Commercial beverages and juices containing different amounts of food dyes were analyzed and the results were compared to those obtained by HPLC.
