THE VOLUMETRIC DETERMINATION OF URANIUM AFTER REDUCTION BY LEAD IN DILUTE PERCHLORIC ACID SOLUTION
A rapid and convenient volumetric method is described for determining uranium which is suitable for high-grade ores and oxide concentrates. A dilute boiling solution of the sample in perchloric acid is reduced with granular lead and cooled under an atmosphere of carbon dioxide. After decanting the solution and adding ferric perchlorate, it is titrated with standard potassium dichromate solution. The elements found to interfere can be removed by precipitation with cupferron in the perchloric acid solution. The results obtained for uranium oxide samples by the proposed method are compared with those by a standard gravimetric method. (auth)
