METHOD OF PREPARING ANION-DEFICIENT URANYL NITRATE SOLUTIONS Russian patent published in 2015 - IPC C01G43/00 C01B21/48

Abstract RU 2568729 C1

FIELD: chemistry.

SUBSTANCE: method includes mixing uranium oxide with water with liquid to solid ratio of 0.1-0.15, adding nitric acid to the obtained pulp while stirring constantly, said nitric acid being added in droplets with molar ratio of the nitrate ion to metal in the solution of 1.6-1.95, filtering the obtained solution and adjusting the density of the solution first, and then pH of the solution at temperature not higher than 12°C by adding urotropin.

EFFECT: efficient production of anion-deficient metastable uranyl nitrate solutions with given characteristics.
