AbstractAbstract
[en] Solvent extraction of Am(III) and Eu(III) was investigated using two hydroxyoctanoic acids including a new 2-hydroxy-2-trifluoromethyl-octanoic acid (L1-CF3) and two bidentate N-heteroaromatic compounds as extractants. The new lanthanide(III) complexes with bidentate N-heteroaromatic ligands were synthesized and the structures were characterized to eight- or nine-coordinate. Solvent extraction of Am(III) and Eu(III) in 1-octanol/acetic acid buffer solution was performed. The separation factor using L1-CF3 was about 2. (author)
