“…Because of the possibility to form water-free complexes with the rare-earth ions, dipivaloylmethane (Hthd) is a much better extracting reagent (Sweet and Parlett, 1968). The synergism in the extraction of trivalent rare-earth ions has been studied by many workers (Healy, 1961a(Healy, , 1961bYoshida, 1966;Scribner and Kotecki, 1965;Shigematsu et al, 1966Shigematsu et al, , 1967Shigematsu et al, , 1969bShigematsu et al, , 1970.…”

“…GENOV and DUKOV [4] studied the extraction of praseodymium with ΗΤΤΑ in the presence of trioctylamine (TOA) in various solvents including chloroform from mineral acid solutions. SCRIB-NER and KOTECKI [5] successfully enhanced the extraction of some divalent metal ions by adding isobutylamine to a ß-diketone namely trifluoroacetone in chloroform. Synergic extraction of Fe(II), Co(II), Cu(II) and Zn(II) by HTTA-dibenzylamine and of Co(II), Fe(III) by HTTAvarious amines including TBA has been recently reported [6][7][8].…”

Synergic effect of tribenzylamine (TBA) on the solvent extraction of Fe (III), Co (II) and Cu(II) by thenoyltrifluoroacetone (ΗΤΤΑ) in chloroform from aqueous medium of ionic strength 0.33 Μ (H + , NaC10") has been studied. For trivalent iron an enhanced extraction >98% was observed at pH 2.5 and the equilibrium was attained within 5 minutes. Extraction parameters such as concentrations of ΗΤΤΑ, TBA and pH were optimised by a triangular co-ordinate graph. The stoichiometry of the extractable adduct Fe(TTA), TBA was established by slope analysis. Extraction and formation constants of extractable species were computed.
