Lithium carbonate was titrated after dissolution in a glacial acetic acid/carbon tetrachloride mixture with 0.05 N perchloric acid in glacial acetic acid in the presence of gentian violet indicator. In the case of lithium nitrate the nitrate was firts reduced with ascorbic acid and the lithium titrated in an acetic anhydride/glacial acetic acid medium with the same measuring solution and indicator. The lithium content of lithium ferrites and lithium-nickel-zinc ferrites was measured after the extraction of iron and nickel by means of methyl-isobutyl ketone in a glacial acetic acid/carbon tetrachloride solution in the presence of tropeoline OO/methylene blue indicator mixture. © 1969 Springer-Verlag.
