Abstract

Nanogram quantities of copper and silver are electrodeposited on a glassy carbon electrode from a hydrofluoricnitric acid solution containing 05–1 g of tantalum The deposit is then anodically removed in 01M hydrochloric acid a currentvoltage curve being recorded The impurities at the parts per billion level in highpurity tantalum metal powder are determined within 3 hoursNanogrammengen Kupfer und Silber werden aus flußsaurer salpetersaurer Lösung von 05–1 g Tantal elektrolytisch an einer Elektrode aus glasartigem Kohlenstoff abgeschieden Während der anodischen Auflösung in Salzsäure wird eine Stromspannungskurve geschrieben Verunreinigungen in der ppbGrößenordnung in hochreinem Tantalpulver lassen sich so innerhalb 3 Stunden bestimmen
