摘要：

The liquid/liquid extraction of Am(III) from nitric acid solutions with chloroform solutions of 2,6 bis[(diphenylphosphino)methyl]pyridine N,P,P' trioxide (ENOPOPO) is examined. Americium(III) is efficiently extracted from aqueous solutions at high nitric acid concentrations (D-Am>3000 at 6M HNO3) and can be totally back extracted from the organic phase at 0.01M HNO3. The ligand dependency data suggest that two ligand molecules are coordinated to the americium. Additional aspects of the extraction mechanism are described.
