Flame Photometric Determination of Lithium Contents Down to 10{sup -3} ppm in Water Samples

Abstract

A flame photometric method has been developed for determination of submicro contents of lithium in water. The intensity of the emission from lithium increases about three times if 20 % of a mixture of acetone - amyl alcohol (4:1) is added to the sample. Interferences by stray light from sodium present is eliminated with a special absorption filter. Interferences from oxide bands of the alkaline earth metals are completely suppressed after adding aluminium to the sample. With the development of this routine method it is possible by flame photometry to directly determine 0.01 ppm lithium with an error of analysis less than 10 %. Furthermore the investigation shows that, after concentration of the sample by evaporation, contents down to 10{sup -3} ppm can be determined without any difficulty. One person can run up to 50 determinations per day.
