Description

The thermodynamics of the extraction of Eu3+ by thenoyltrifluoroacetone (HTTA) and by mixtures of HTTA and bidentate amine bases such ad 2,2'-dipyridyl (Dipy) and 1,10-phenanthroline (Phen) in benzene from an aqueous phase fixed to 0.1M ionic strength (NaClO4), pH 3.9, has been investigated. Phenanthroline forms both the Eu(TTA)3*Phen and Eu(TTA)3*2Phen species, which are much stronger than the dipyridyl complexes. The diluent effect on the extraction is also studied.
