Research On Determination Of U(IV) And U(VI) In Uranium Ore
- 1. Center for Analytical Chemistry, Institute for Technology of Radioactive and Rare Elements, Hanoi (Viet Nam)
Description
In this project, we have researched on the method for determination of U(IV) and U(VI) in uranium ore. Uranium ore is decomposed with concentrate hydrofluoric acid (HF). U(VI) is dissolved and remained in the solution. U(IV) is also dissolved and combined with F- ion in the solution to form precipitate UF4 that is settled. Two valence forms of uranium are separated from each other and determined by suitable methods. The method was well applied to determine contents of U(IV) and U(VI) in uranium ores with different weathering levels. (author)
