Abstract:  The coordination properties of three dyes of the Alizarin Green series and vanadates were studied in the presence of Septonex. The defined ternary complexes VL₂S₄ and VL₂S₆ arise in weakly acid medium of pH 2—6.5. The equilibrium constants of the studied complex formation were calculated and a method of photometric determination of vanadium was proposed.
