; ;
A spectrochemical method is described for the determination of hafnium in zirconum witn concentration range 4.10/sup -4/ to 4.10/sup -2/%. Six standards were prepared by mixing known quantities of spectroseopically pure hafnium and zirconium oxides. Their hafnium concentrations were graph employed is of the type ISF-22 with a slit width of 0.030mm. Line pairs for comparison used in this procedure were: ZrII 2568 873 and HfII. 2641. 406 A. A plot of the logarithm of the hafnium concentration versus the change in line darkening is presented. The mean square error in the determination of hafnium concentration is about 5% in the range 8.10/sup -4/%. (TTT)
