抄録

A spectrographic method has been developed for the simultaneous determination of chromium, iron, nickel and tin in zircaloy-2. Analyses were made on samples in the form of solid machined specimens 30 mm in diameter. Spectra were excited with a low voltage spark (multisource type) in argon atmosphere and recorded on a photographic plate with the Ebert mounting spectrograph. Zirconium was used to serve as the internal standard.<BR>Various kinds of counter electrodes, such as graphite, silver, copper, aluminium, zinc, tungsten and iron, were investigated. The effects of them on the results were small enough in an optimum analytical condition.<BR>Precision of the presented method was 3∼7% in coefficient of variation and the method was accurate enough to be utilized to check compliance with specifications.
