This paper deals with the spectrographic method for the simultaneous determination of trace elements (Al, Co, Mg, Mn, Mo, Pb, Ti and V) in zircaloy-2.
Satisfactory results were obtained by using “Oxide-D.C. Arc Technique” which has two advantages from a viewpoint of spectrochemical analysis, that is, the simple preparation of standard samples and the high sensitivity.
A mixture of the oxide sample and graphite powder containing Y₂O₃ as an internal standard was arced for 15 sec 7 amp. d.c. arc, with sufficient sensitivity and high precision. The density of spectra obtained was measured by an automatic recording microphotometer, and then converted into the relative intensity by means of special calculator “Respectra”.
The coefficient of variation was from 5 to 20% in the analytical concentration range from 5 to 200 ppm.
