Résumé

Parmi les dihydrazides des acides dicarboxyliques, le plus intéressant est celui de l'acide malonique qui fournit un réactif qualitatif spécifique du palladium. Le dosage gravimétrique ne s'applique pas, mais la colorimétrie permet d'évaluer de 2 à 10μg/ml de palladium, à 285 nm.

Zusammenfassung

Unter den Dicarbonsäure-Dihydraziden ist das interessanteste das der Malonsäure. Es ist ein für Palladium spezifisches Nachweisreagens. Zur gravimetrischen Bestimmung eignet es sich nicht, aber kolorimetrisch kann man bei 285 nm 2 bis 10μg Pd/ml bestimmen.

Summary

The most interesting of the dihydrazides of dicarboxylic acids is that of malonic acid, which yields a qualitative specific reagent for palladium. The gravimetric determination is not practicable but the colorimetric method permits the evaluation of from 2 to 10μg/ml of palladium at 285 nm.
