Atomabsorptionsspektroskopische Bestimmung von Edelmetallen 4. Beeinflussung der Platinbestimmung durch Palladium und Rhodium

Atomic-Absorption Spectroscopic Determination of Noble Metals. 4. Influence of Palladium and Rhodium on the Determination of Platinum. There are a number of serious interferences in the determination of platinum by atomicabsorption spectrometry. The influences of palladium and rhodium have been investigated. It is shown that they can be eliminated by an addition of uranium and by quadratic correction equations. Addition of lanthanum is not suitable.
