The liquid/liquid extraction of Am(III) from hydrochloric acid solutions with chloroform solutions of 2,6-bis[(diphenylphosphino)methyl]pyridine N,P,P{prime}-trioxide (ENOPOPO) is described. ENOPOPO exhibits modest extraction ability for americium(III) (D{sub Am} = 2.2 at 5 M HCl) and can be efficiently back extracted from the organic phase at 0.1 M HCl. The ligand dependency data suggest that three ligand molecules are coordinated to the americium in the extraction complex. Additional aspects of the extraction mechanism are described.
