Determination of uranium in phosphogypsum
A method for determination of uranium in phosphogypsum is based on extraction of uranium from phosphoric acid in which hydration transformations of calcium sulphate hydrates have occurred. The uranium is extracted with a kerosene solution of a mixture of mono- and dinonylphenylphosphoric acids, then...

| Summary: | A method for determination of uranium in phosphogypsum is based on extraction of uranium from phosphoric acid in which hydration transformations of calcium sulphate hydrates have occurred. The uranium is extracted with a kerosene solution of a mixture of mono- and dinonylphenylphosphoric acids, then stripped with concentrated phosphoric acid, and determined spectrophotometrically with Arsenazo III. |
