SOLVENT EXTRACTION WITH THE DI-ISOAMYL ESTER OF METHYL-PHOSPHINIC ACID (in Russian)

Journal Article · · Atomnaya Energ.
OSTI ID:4246803
Solvent extraction of uranium with the di-soamyl ester of methyl- phosphinic acid (DAMPA) is described. A high efficiency for extraction from nitric acid solutions is achieved. Centain regularities in extraction by DAMPAhydrated kerosene systems are studied. The uranyl antrate is extracted in the form STAUO/sub 2/(NO/sub 3/)/sub 2/ (DAMPA)/sub 2/! with a stability constant 2540 plus or minus 200; HNO/sub 3/ is extracted as HNP/sub 3/DAMPA with a stability of 0.30 plus or minus 0.03.
