Title: Method for preparing uniform dispersed solid between alkaline earth metal and uranium by drying liquid- containing precipitation
Inventor: FUJINO TAKEO
IPC: C01G43/00
Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To obtain a dispersion solid without requiring such labor and time as mechanical mixing and such high temperature as melting mixing by precipitating only uranium salt from a solution containing an alkaline earth metal ion and a uranium ion and drying precipitation containing the solution. SOLUTION: When ammonium is added to a dilute mineral acid solution containing a uranyl ion such as nitric acid uranyl, the settlement of a biuranic acid ammonium(ADU) is generated. The ADU is a yellow-white creamy, viscous precipitation and has high water-retaining capacity. Therefore, only the ADU is precipitated from a solution containing both a metal ion and a uranyl ion to be mixed while allowing the metal ion to remain in the solution, thus homogeneously mixing uranium and target metal in a obtained solid by drying the precipitation without washing since the settlement retains a small amount of partial solution.
