Synergic Effect of Tribenzylamine on the Extraction of Fe (III) with 2-Thenoyltrifluoroacetone in Chloroform

Abstract

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.

Radiochemical Separation of Fe(lll), Co(ll), Zn (II) and Sc (III) Using 2-Thenoyltrifluoroacetone- Tribenzylamine Synergie Extraction System

“…In our previous communication [1 ] we have described the synergic effect of tribenzylamine (TBA) on the extraction of Fe (III) with 2-thenoyltrifluoroacetone (TTA) from aqueous acidic media. The synergic extraction systems help to increase the reaction selectivity and sensitivity and can be employed for the development of simple and rapid radiochemical separation procedures for use in activation analysis [2].…”
