Microchimica Acta Aims and scope Submit manuscript

Summary

A spectrophotometric method has been developed for the determination of ruthenium. The method is based on the magenta coloured complex (absorption maximum — 530 nm) formed when ruthenium and 4,5-diamino-6-hydroxypyrimidine sulfate are heated together in a slightly acidic solution. The molar absorptivity of the magenta coloured complex solution is 6.5 × 103 liter mole−1 cm−1.

Zusammenfassung

Eine spektrophotometrische Methode zur Rutheniumbestimmung wurde ausgearbeitet. Sie beruht auf der Bildung einer purpurroten Komplexverbindung (Absorptionsmaximum: 530 nm), die sich beim Erhitzen von Ruthenium und 4,5-Diamino-6-hydroxypyrimidinsulfat in schwach saurer Lösung bildet und deren Extinktionskoeffizient 6,5 × 103 l Mol−1 cm−1 beträgt.
