  • Published:
Microchimica Acta Aims and scope Submit manuscript

Summary

A procedure is described suitable for determining iron and gallium down to the levels present in 99.999% pure aluminium. Copper, cobalt, manganese, and lanthanum do not interfere. A single determination takes about two hours.

The precision of the method is within 0.1μg iron at the 2-μg iron level and within 0.4μg of gallium at the 2-μg gallium level per gram of metal.

Zusammenfassung

Ein Verfahren zur Bestimmung von Bisen und Gallium in 99,999%igem Aluminium wird beschrieben. Kupfer, Kobalt, Mangan und Lanthan stören nicht. Eine Einzelbestimmung dauert ungefähr 2 Stunden. Die Genauigkeit des Verfahrens beträgt 0,1μg Fe und 0,4μg Ga bei Anwesenheit von 2μg des betreffenden Elementes pro Gramm Metall.

Résumé

On décrit un procédé permettant le dosage du fer et du gallium jusqu'aux teneurs présentes dans l'aluminium pur à 99,999%. Le cuivre, le cobalt, le manganèse et le lanthane n'interfèrent pas. Un seul dosage demande environ 2 heures.

La précision de la méthode est de 0,1μg de fer pour 2μg de fer présent et de 0,4μg de gallium pour 2μg de gallium présent par gramme de métal.
