Abstract

A method for the determination of barium by conductometric
titrn.tion in the precipitates of the system uranyl nitrate -potassium
hydroxide - barium nitrate, is proposed. The precipitates
were dissolved in concentrated nitric acid and uranium
separated by means of continuous extraction with tetrahydropyrane.
Barium could be determined from 0,.6 to 7 mg with a
standard error of about 0.12 mg Ba. The lowest gramatomic ratio
Ba/U was 1.8 X 10-4.
