Abstract

The distribution of some metal ions in the water – catamin AB – NH4NO3 segregated system in the presence of dyes – alizarincomplexon, sulfarasazene, bromopyrogallic red, pyrogallic red, pyridyla- zonaphthol, capable of forming colored complexes with metals have been considered. The possibility of extraction-photometric determination of lead with pyrogallic red and copper with pyridylazonaph- thol have been shown.
