A simple and accurate method, which can be employed for routine work in the laboratory, was worked out for the estimation of free acid in uranyl nitrate solutions. Uranium is complexed with Na sulfate and separated by adsorption on an anion exchange resin column in sulfate form. The free acid, which is also adsorbed as bisulfate, is selectively eluted with a dilute solution of Na sulfate, and titrated with standard alkali. About 0.3 mmole of HNO/sub 3/ can be accurately estimated in the presence of up to 1.3 mmoles of U. Alkali and alkaline earth metals and Mg do not interfere in the determination whereas Fe, Al, Th, Ti, Zr, and rare earth elements do interfere. The method compares well in accuracy with the ferrocyanide and peroxide methods. (auth)
