    Description / Table of Contents: Zusammenfassung Vanadin bildet bei pH 8,10 (Tris-HClO4-buffer) mit 4-(1′H-1′,2′,4′-tri-azolyl-3′-azo)-2-methylresorcin ein rosenrot-violettes Chelat, dessen Absorptionsmaximum bei 525 nm in Gegenwart von 50% Methylalkohol gemessen wird. Dieser 1∶1-Komplex entspricht bei einer Vanadin-Konzentration von 0,1–1,51μg/ml dem Beerschen Gesetz; seine molare Absorptivität ist 2,55×104l·mol−1·cm−1. Das Verfahren wurde zur Bestimmung des Vanadins in Stahl verwendet.
    Notes: Summary 4-(1′H-1′,2′,4′-Triazolyl-3′-azo)-2-methylresorcinol reacts with vanadium(V) at pH 8.10 (Tris-HClO4 buffer solution) to produce a pink-violet 1∶1 complex (λ max=525 nm,ε=2.55×104l·mol−1· cm−1) in a 50% (v/v) methanol-water medium, which allows the spectrophotometric determination of 0.1 to 1.51 ppm of vanadium. The method has been applied for the determination of the vanadium content in low alloy steels.
