Abstract

The polarographic behavior of five water-insoluble azo pigments was studied in an acetonitrile medium. The diffusion character of the observed limiting currents was confirmed and a mechanism was proposed for the polarographic reduction. The possibility of an analytical application is briefly discussed.
