Saeed, M. Mufazzal published the artcileSynergic extraction of Eu(III) with 3-methyl-1-phenyl-4-trifluoroacetyl-2-pyrazolin-5-one (HPMTFP) and tribenzylamine (TBA) from perchlorate media, Recommanded Product: 5-Methyl-2-phenyl-4-(2,2,2-trifluoroacetyl)-1H-pyrazol-3(2H)-one, the main research area is extraction europium fluoroacetylpyrazolinone benzylamine aqueous perchlorate; formation constant europium complex synergic extraction; partition europium extraction fluoroacetylpyrazolinone benzylamine.
Synergic extraction of hydrolyzable lanthanide Eu(III) was studied at low pH range with 0.05 M (HPMTFP + TBA) in CHCl3 from aqueous perchlorate media. The composition of the adduct was established as Eu(PMTFP)3·TBA and Eu(PMTFP)3·2TBA under the conditions of 0.01 M ≥ TBA. The formation constants Ka, Ksyn1, and Ksyn2 and stability constants β1, β2, and K2 of the organic phase reaction were calculated Among the various anions and cations tested, fluoride, oxalate, phosphate, EDTA, Cu(II), and Ti(IV) have drastically reduced the extraction of Eu, whereas oxalate partially reduces the extraction
