Zusammenfassung

Es wurden neue Methoden zur mikrogravimetrischen Bestimmung des Kupfers und des Zinks beschrieben. Als Fällungsreagenzien verwendet man wäßrige o-Phenanthrolinoderα,α'-Dipyridylhydrochloridlösungen in Gegenwart von Ammoniumthiocyanat. Die Methoden gestatten auch die Bestimmung des Kupfers und des Zinks in Gegenwart der Elemente Na, K, Ca, Sr, Ba, Mg, Al, Cr, Sc und von NH4 +-Ionen.

Summary

New methods are described for the microgravimetric determination of copper and zinc. The precipitants are aqueous solutions ofo-phenanthroline orα,α'-dipyridyl hydrochloride in the presence of ammonium thiocyanate. The methods also permit the determination of copper and zinc in the presence of the elements Na, K, Ca, Sr, Ba, Mg, Al, Cr, Sc, and NH4 +-ions.

Résumé

On décrit de nouvelles méthodes de dosage microgravimétrique du cuivre et du zinc. On emploie comme réactif précipitant, des solutions aqueuses d'o-phénanthroline ou de chlorhydrate d'α,α'-dipyridyle, en présence de thiocyanate d'ammonium. Les méthodes permettent aussi le dosage du cuivre et du zinc en présence des éléments Na, K, Ca, Sr, Ba, Mg, Al, Cr, Sc et des ions NH4 +.
