Summary

Palladium and uranium react with 4,4-acetalidine-bis-(3-methyl isoxazolone-5) in acid medium to give yellow color having a visual limit of identification at 2 and 15μg per ml. This color reaction provides the basis of a new method for colorimetric determination of palladium and uranium. Copper also gives yellow color but it cannot be determined with this color reaction because the color intensity is not stable. The maximum tolerable limit of various ions is reported.

Zusammenfassung

Pd und U reagieren in saurem Milieu mit 4,4-Acetalidin-bis-(3-methyl-isoxazolon-5) unter Gelbfärbung mit einer Erfassungsgrenze von 2 bzw. 15μg/ml. Diese Farbreaktion dient als Grundlage für eine neue kolorimetrische Methode für Pd und U. Cu gibt zwar auch eine Gelbfärbung, kann aber damit nicht bestimmt werden, da die Farbintensität nicht beständig ist. Die maximal tolerierbare Menge der Fremdionen wird angegeben.
