Photometric determination of palladium with 3-nitroso-2,6-pyridinediol

Microchimica Acta volume 58, pages 474–477 (1970)Cite this article

Summary

A highly sensitive and selective photometric method has been developed for the determination of palladium. The method is based on the yellow complex (absorption maximum-430 run) formed when palladium and 3-nitroso-2,6-pyridinediol are heated together in 0.1M perchloric acid. The reaction ratio is 2∶1 reagent to palladium. The molar absorptivity of the yellow complex is 2.6 · 104 liter mole−1 cm−1. Only platinum (IV), ruthenium (III), and iron(III) seriously interfere among the common and platinum metals.

Zusammenfassung

Eine sehr empfindliche und selektive photometrische Methode zur Palladiumbestimmung wurde ausgearbeitet. Sie beruht auf dem gelben Komplex (Absorptionsmaximum bei 430 nm), der sich beim Erwärmen aus Palladium und 3-Nitroso-2,6-pyridindiol in 0,1-n Perchlorsäure bildet. Reagens und Metallion reagieren im Verhältnis 2∶1. Die molare Absorption beträgt 2,6 · 104 1 mol−1 cm−1. Nur Platin(IV), Ruthenium(III) und Eisen(III) stören die Bestimmung.
