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.
