SPECTRAL ANALYSIS OF IMPURITIES IN ZIRCONIUM AND ITS COMPOUNDS
A study was made of a direct spectral method which allows the simultaneous determination of 24 elements in zirconium and its compounds with high sensitivity and reasonable accuracy. The method is based on the use of a discharge in a hollow cathode. The temperature of the sample, which is in the cathode at constant discharge parameters, is unambiguously related to the discharge current. This makes it possible in principle to reduce considerably the influence of the third components in determining a large group of elements due to a more complete application of the fractional evaporation principle. In the case of many elements it is possible to use absolute blackening due to the great stability of the source of light, while in the other cases the employment of the internal standard considerably improves the calibration curves and the reproducibility of the results. The application of the method suggested saves labor and time in analyzing zirconium and its compounds compared with conventional methods. By using the methcd, it is possible to deterrtdne the impurities in zirconium with high sensitivity, and such determinations, though not optimal, meet the requirements for the quality of zirconium amd its compounds.
