OSTI ID:4189810
BS>A method is described which permits the quantitative determination of zirconium in minerals and rocks at a zirconium concentration of 0.02 to 100% ZrO/ sub 2/. The excitation is rade with a 10 amp direct current arc between carbon electrodes. The sample is placed in a 2-mm deep crater. For low concentration the sample is diluted with its own weight in carbon powder and 4% its weight in Co/sub 3/O/sub 4/ (internal standard). The lines used are the Zr 2571.4, Co 2585.3, and Co 2587.2 A lines. For high concentrations the sample is diluted with GeO/sub 2/ (spectroscopic buffer), carbon powder, and CuO (diluent and internal standard). The Zr 2571.4 and Cu 2768.9 A lines are used. Excellent results are obtained. The mean relative deviation with respect to chemical results is 7.7%. (tr-auth)
