Выдержка

Direct current and differential pulse polarograms of reactive triazine- based azo dyes containing 4-carboxypyridyl and 1,4-diazabicyclo[2,2,2]octanyl (DABCO) leaving groups show one wave or peak corresponding to reduction of the azo group and other waves or peaks at more negative potentials corresponding to the reduction of reactive groups. Optimum conditions were found for polarographic and voltammetric determination at submicromolar concentrations of the test dyes based on azo group reduction. The peaks corresponding to the reduction of the reactive group can be used for monitoring the hydrolysis of the test dyes.
