OSTI ID:4222495
The determination of lithium in barium chloride is unsatisfactory in the presence of strontium. A new method of preparing a concertrate of lithium for spectrographic examination by the Lundegardh technique is described. The bulk (95%) of the barium is first removed as sulfates leaving all the lithium and strontium in solution; the remainder of the barium (5%) is then precipitated as sulfate in alcohol. All the strontium is co-precipitated with the barium and the lithium is left free from strontium in solution When small quantities of the order of 5 to 20 gamma g lithium were added to solutions of 5 g barium chloride (i.e., l to 4 ppm) satisfactory ''recovery'' was obtained. The new method has also the advantage that hydrochloric acid is eliminated from the concentrate before it is spectrographed, thus avoiding suppression of the lithium line 6707.8 A by hydrochloric acid.
