ION EXCHANGE SEPARATION IN THE ANALYSIS OF BISMUTH BASE ALLOYS. PART II. TERNARY ALLOYS CONTAINING URANIUM AND THORIUM
Procedures are described for the analysis of bismuth base alloys containing uranium and thorium in the range from 0.1 to 10%. The thorium is first separated by the passage of a solution of the sample in 5M hydrochloric acid through a column of Deacidite FF in the chloride form. For thorium contents greater than about 1%, the determination is completed volumetrically with EDTA using pyrocatechol violet as the indicator. Smaller amounts are determined absorptiometrically by the thoronol method. Uranium is recovered from the ion- exchange column in a quantity of U.2M hydrochloric acid, bismuth still being retained by the column under these conditions. Uranium contents greater than about l% are determined volumetri-cally after reduction to the tetravalent state with a lead reductor, while smaller amounts are determined pelarographically using a tantrate base solution.
