Summary

Methods for the gravimetric micro-determination of copper, zinc and nickel separately and separations of Cu-Zn and Cu-Ni, using diallyl dithiocarbamido-hydrazine as reagent, are described. Separation is achieved by pH-control.

Zusammenfassung

Verfahren zur getrennten, gravimetrischen Mikrobestimmung von Kupfer, Zink und Nickel sowie zur Trennung von Kupfer und Zink bzw. Kupfer und Nickel mit Hilfe von Diallyldithiocarbamidohydrazin als Fällungsreagens werden beschrieben. Die Trennungen lassen sich durch Einhaltung bestimmter PH-Werte erzielen.

Résumé

On décrit des méthodes de microdosage gravimétrique du cuivre, du zinc et du nickel séparément et des méthodes de séparation de Cu-Zn et de Cu-Ni, en utilisant comme réactif la diallyl dithiocarbamido hydrazine. La séparation s'effectue à PH donné.
