OSTI ID:4183209
A method was devised for the determination of free acidity in aqueous uranyl nitrate solutions. The method depends upon the use of a reagent which complexes the uranium and the major impurities and the salt of an organic acid possessing a favorable dissociation constant, in addition to a suitable partition coefficient with respect to water and immiscible organic solvents. By this means, an equivalent quantity of the organic acid, in the present case benzoic acid, is liberated by the free nitric acid and is transferred into the solvent layer, chloroform, while uranium is complexed by potassium oxalate. The solvent layer, containing the liberated organic acid is titrated with alcoholic potassium hydroxide. (auth)
