Process for Production of Uranium Compounds of Nuclear Purity

摘要

Impurities are removed from U by precipitating from an aqueous solution as ammonium uranyl carbonate. The solution contains 200 to 450 g/l U as uranyl nitrate, and the precipitation is carried out at 40 to 60 exp 0 C and at a pH between 7.5 and 9. (ERA citation 04:025569)
