Abstract

Rubidium uranium trisulphate [Rb₂U(SO₄)₃] was prepared as a high purity compound of uranium in different lots of 250 g each. The compound was characterised and evaluated by chemical, atomic spectrosopic, infrared, X-ray diffraction and thermogravimetric methods for its use as a chemical assay standard for uranium. The compound is stoichiometric, pure, homogeneous and stable in atmospheric conditions. The solubility studies showed that Rb₂U(SO₄)₃ is easily soluble in mineral acids. An experiment based on Randomised Block Design was carried out to assign a value to the uranium content in Rb₂U(SO₄)₃ from the statistically analysed chemical data. The assigned value of [34.167±0.042]% to the uranium content is in close agreement with the theoretical value of 34.152%. Based on these studies, Rb₂U(SO₄)₃ is recommended as a chemical assay standard for uranium.
