Abstract

The interaction of molybdochromic heteropolyacid with Crystal Violet basic dye has been studied. The optimal conditions for formation of molybdochromic hetcropolyacid and its compound with Crystal Violet have been estimated: acidity of medium, concentration of molybdate-ion, concentration of dye, the range of chromium contents submitted to the Beer’s law. The composition of complex ionic associate has been determined. Photometric method of nanogramic amounts of chromium has been worked out.
