Description

An X-ray fluorescence method is described for the determination of Sm, Eu, Tb, Dy, Ho, Yb and Y in gadolinium oxide. Samples are taken in oxalate form and mixed with boric acid in the ratio 3:1. The mixture is pressed as a double-layer pellet. Selection of experimental parameters and choice of analysis lines is discussed. The estimation limit ranges from 0.005-1% for most of the elements. (orig.)

Abstract (German)

Bei dem vorgeschlagenen Verfahren werden die Proben in die Oxalatform uebergefuehrt und mit Borsaeure im Verhaeltnis 3:1 gemischt. Die Mischung wird zu einer Doppelschicht-Tablette gepresst. Die Auswahl der geeigneten experimentellen Parameter sowie der Analysenlinien wird diskutiert. Die Bestimmungsgrenzen liegen fuer die meisten Elemente im Bereich 0,005-1%. (orig.)
