Abstract: The sample of fused fluoride was dissolved in H₂O or in a satd. soln. of H₃BO₃ in HCl. The solns. were analyzed by flame photometry on the basis of calibration curves for varying amts. of Li and Na. The samples contained 0.1-26.0% Li and 0.4-54.0% Na, and Li:Na ratio 1:600 to 60:1. Li and Na were detd. by spectral anal. in the O-C₂H₂ flame at 670.8 mμ and 589.3 mμ, resp. on a CF₄ spectrophotometer. The measuring ranges were 5-50 mg. Li/l. and 5-400 mg. Na/l. The relative error of 1 detn. of Li or Na was <3.0%.
