The optimal reaction conditions for CAN and V (V) and Se (VI) ions were established; the main chemical and analytical characteristics of target products were calculated that have been tested, as new forms of analytical determination of these metals and the basis for the selective and sensitive spectrophotometric determination methods of V (V) and Se (VI) in the presence of Mn (VII) and Cr (VI) in food, medicinal herbs and drugs, as well as in the waters of the various categories.
