Photometric Determination of Palladium With 3-Nitroso-2,6-Pyridinediol
Chemistry and Biochemistry
Mathematics and Natural Sciences
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.
