Summary

A method of spectrophotometric analysis for ruthenium, using the reagent 1-pentyl 4,6-dihydroxy-5-nitrosopyridine-3-carboxylate, has been developed. Several interferences are removed by extraction prior to the developemnt of the purple color formed between PDNHPC and ruthenium. The molar absorptivity of the PDHNPC-ruthenium complex is 4.2×104 at 535 nm. The complex forms at a 3∶1 ligand-metal ratio. This procedure provides the most sensitive colorimetric method for the determination of ruthenium.

Zusammenfassung

Ein Verfahren zur spektrophotometrischen Bestimmung von Ruthenium unter Verwendung von 1-Pentyl-4,6-dihydroxy-5-nitrosopyridin-3-carboxylat als Reagens wurde ausgearbeitet. Verschiedene Störfaktoren wurden durch Extraktion vor Entwicklung der purpurroten Färbung mit Ruthenium entfernt. Die molare Extinktion der Komplexverbindung beträgt 4,2x104 bei 535 nm. Das Verhältnis Ligand zu Metall beträgt 3∶1. Das angegebene Verfahren bietet die empfindlichste kolorimetrische Methode zur Bestimmung von Ruthenium.
