THE DETERMINATION OF IRON IN AMMONIUM DIURANATE AND URANIC LIQUORS

Technical Report ·
OSTI ID:4292399

The ammonium diuranate is dissolved in nitric acid. An aliquot equivalent to 1 g of uranium is treated with sulfamic acid to suppress interference by nitrite, and the thioglycolic iron complex developed in the presence of ammonium carbonate and ammonium citrate is determined absorptiometrically. The method is suitable for the determination of iron concentrations between 0 to 300 ppm. The amount of uranium must, however, not exceed 1.5 g. (auth)
