Summary

A method is outlined for the gravimetric determination of small amounts of technetium and rhenium, using the Oertling quartz-fibre ultramicrobalance. Tetraphenylarsonium chloride is used as the reagent in both determinations, and a method for separation of the two elements from each other is proposed.

Zusammenfassung

Eine Methode für die gravimetrische Bestimmung kleiner Mengen von Technetium und Rhenium mit einer Quarzfaser-Ultramikrowaage von Oertling wird beschrieben. Für beide Bestimmungen dient Tetraphenylarsoniumchlorid als Reagens. Ein Verfahren zur Trennung der beiden Elemente voneinander wird vorgeschlagen.

Résumé

On indique une méthode pour le dosage gravimétrique de petites quantités de technétium et de rhénium, en utilisant l'ultramicrobalance à fibre de quartz d'«Oertling». On utilise comme réactif, le chlorure de tétraphénylarsonium dans les deux dosages, et l'on propose une méthode de séparation des deux éléments.
