Joint Solubility of Uranyl(VI) and Plutonyl(VI) Nitrates in Nitric Acid Solutions
摘要
Abstract
The solubility of plutonyl(VI) and uranyl(VI) nitrates in nitric acid solutions taken in the ratios Pu/(Pu + U) = 0.3 ± 0.015 (main data), Pu/(Pu + U) = 0.25 ± 0.025, and Pu/(Pu + U) = 0.5 ± 0.025 (single compositions) at +25, +15, and +5°C (±3) was determined by the method of isohydric crystallization. The calculated solubility isotherms of plutonyl(VI) and uranyl(VI) nitrates are presented in a wide range of nitric acid concentrations.
