Procedures are described for the determination of U (0.001 to 10%) and Th (O.O5to 10%) in binary mixtures with Bi. A preliminary separation of the Bi is effected by the passage of a HCl solution of the sample through a column of Deacidite FF. For Th contents greater than 1%, the determination is completed volumetrically with EDTA using pyrocatechol violet as indicator; smaller amounts are determined absorptiometrically with thoronol. Similarly the higher U contents are determined volumetrically after reduction to the tetravalent state with a Pb reductor, and an absorptiometric method based on the colored complex formed by U/sup 4+/ with thoronol is used for the smaller amounts.
