Evaluation of ruthenium contents in powder residues by X-ray fluorescence analysis
Description
A method is described of evaluating ruthenium in powder samples, using an energy dispersive x-ray fluorescence spectrometer. Disturbing influences by accompanying elements (mainly molybdenum, and zirconium, iron, lead and other elements in addition) are suppressed either by adequate dilution with SiO2 of the sample material (thick samples) or by preparing thin filter samples. The method yields accuracies around +-10%, resulting essentially from the errors due to the development of the superimposing K-X-ray spectra of zirconium, molybdenum, and ruthenium. Within these limits of error comparable results are obtained also in ruthenium evaluation by activation analysis in these residual samples. (orig.)

Eine Methode zur Bestimmung von Ruthen in pulverfoermigen Proben unter Verwendung eines energiedispersiven Roentgenfluoreszenzspektrometers wird beschrieben. Stoereinfluesse von Begleitelementen (hauptsaechlich Molybdaen, daneben Zirkon, Eisen, Blei und andere) werden entweder durch ausreichendes Verduennen des Probenmaterials mit SiO2 (dicke Proben) oder durch Herstellen duenner Filterproben unterdrueckt. Das Verfahren liefert Genauigkeiten um +- 10%, die im wesentlichen auf die Fehler bei der Entfaltung der sich ueberlagernden K-Roentgenspektren von Zirkon, Molybdaen und Ruthen zurueckzufuehren sind. Innerhalb dieser Fehlergrenzen vergleichbare Ergebnisse werden auch bei der Ruthenbestimmung durch Aktivierungsanalyse in diesen Rueckstandsproben erhalten. (orig.)
