Summary

A method is proposed for the determination of small amounts of CN or of mixtures of CN and [Ag(CN)2]. The method is based on the use of filter paper impregnated with Ag2CrO4, AgCl or AgBr, and permits the determination of 8–80μg of CN or of 20–200μg of [Ag(CN)2] with an accuracy of 1.5%.

Zusammenfassung

Ein Verfahren zur Bestimmung kleiner Mengen Cyanid oder Mischungen von Cyanid mit Cyanoargentat wird vorgeschlagen. Mit Silberchromat,-chlorid oder -bromid imprägniertes Filterpapier dient zur Bestimmung von 8 bis 80μg Cyanid bzw. von 20 bis 200μg Cyanoargentat mit einer Genauigkeit von 1,5%.

Résumé

On propose une méthode pour doser de petites quantités de CN ou des mélanges de CN et de [Ag(CN)2]. La méthode est fondée sur l'emploi d'un papier filtre imprégné de Ag2CrO4, AgCl ou AgBr; elle permet le dosage de 8 à 80μg de CN ou de 20 à 200μg de [Ag(CN)2] avec une précision de 1,5%.
