Karmoazin as a single redox reagent is proposed for spectrophotometric determination of Mn, Cr, Se, and V in case of their joint presence in different categories of water. It has been found out that the main parameters of complexation reactions of the specified metal ions with karmoazin determining its selectivity include the redox potential of redox pairs of metals, medium acidity and temperature. It was shown that the ions of macro base intrinsic to water bodies did not interfere with determination of Mn, Cr, Se, and V in a wide range of concentrations.
