Spectrographic method for the quantitative determination of small amounts of zirconium in copper-zirconium alloys from solution
Description
For the determination of zirconium concentrations in Cu-Zr-alloys a spectral analysis method based on solutions is described. The sample is dissolved in nitric acid, evaporated together with spectral carbon and pressed to form an electrode which is submitted to spectral investigation. Under the conditions proposed 0.05 to 0.5% of Zr can be determined with a relative standard deviation of 5%. (orig.)
Abstract (German)
Zur Bestimmung von Zirkonium in Cu-Zr-Legierungen wird ein loesungsspektralanalytisches Verfahren beschrieben. Die Probe wird in Salpetersaeure geloest, mit Spektralkohlepulver eingedampft und zu einer Elektrode verpresst, die spektralanalytisch untersucht wird. Unter den ausgewaehlten Versuchsbedingungen koennen 0,05 - 0,5% Zr in Cu-Zr-Legierungen mit einer relativen Standardabweichung von 5% bestimmt werden. (orig.)Additional details
