da Silva, F; de Moura, L

A method is described for the determination of small amounts of U/sub 3/ O/sub 8/ making use of the displacement of the lacto-form to the quinone-form of Rodamine B by the action of uranyl salts of carboxylic acids soluble in benzene. The color is estimated spectrophotometrically, the Beer law being perfectly followed for 5 to 80 gamma /ml of U/sub 3/O/sub 8/. The best operating conditions are selected and the main interferences considered. These are specially Fe, Sn, Mn, Sb, and Tl. Since Cu and Al do not interfere, the classical scheme of separation may be followed. Some analysis results of poor uranium minerals are shown in comparison with the results obtained by other methods. (auth)
