Adsorption preconcentration of synthetic anionic food dyes

详细

The review is devoted to the consideration of adsorption preconcentration of synthetic anionic food dyes for their subsequent determination in various samples. The main classes of adsorbents and their features, conditions for extraction and desorption of the compounds to be determined in batch and dynamic modes, characteristics of procedures using adsorption preconcentration, and examples of their application to the determination of dyes in various food products are given.
