Abstract
The proposed method of photometric analysis for determining content of copper (III) consists in dissolving the sample in nitric acid, treating the solution with reagent in medium containing 20 ... 30 % (by volume) of acetone, and accomplishing photometric analysis of the solution after the intensity of the reagent color has been reduced. As the reagent, alkali dye such as N,N'-dimethylindotricarbocyanine is used.
