The variable internal standard method is applied to the spectrographic determination of impurities (Ni, Cr, Mn, Mg, Si, and Al) in uranium oxides. Iron contained inherently in the sample as an impurity is used as the internal standard element, the content of which has been determined photometrically with 8- quinolinol. The reproducibilities of the determinations of the elements above are improved considerably. The carrier-distillation method is adopted as the excitation procedure. Correction curves and working curves for the respective elements are prepared by the statistical method proposed by Calder. Different combinations of analytical line and reference line give widely different reproducibilities of intensity ratios, and the suitable analytical line pairs are determined experimentally. Better than 10% reproducibilities are obtained for 5 to 100 ppm each of the elements above. (auth)
