Abstract

The influence of water and perchloric acid on the polarographic behavior of some water-insoluble azo pigments in acetonitrile has been investigated. The conditions were defined for the polarographic determination of the test substances in a mixed acetonitrile-water medium. The presence of strong acids prevents analytical use of these reactions.
