AM(III) EU(III) SEPARATION AT LOW PH USING SYNERGISTIC MIXTURES COMPOSED OF CARBOXYLIC-ACIDS AND NEUTRAL NITROGEN POLYDENDATE LIGANDS/

This paper deals with a potential An(III)/Ln(III) separation system ba sed on the use of synergistic systems composed of alpha-substituted ca rboxylic acids and polydendate nitrogen soft donor ligands, 2,2':6',6 '' terpyridine (Tpy) and 2,4,6-tri-2-pyridyl-1,3,5-triazine (TPTZ), an d their respective lipophilic derivatives. The first experiments conce rn Am(III)/Eu(III) separation as a model for An(III)/Ln(III) group sep aration. (C) 1998 Elsevier Science S.A.
