Solvent extraction of iron(III) in aqueous sodium perchlorate solutions with trifluoroacetylacetone in carbon tetrachloride and the complex formation of the metal ion with this ligand in the aqueous phase have been measured at 298 K. It was found that the extraction was quantitative at lower pH than with acetylacetone and the rate is higher than with 2-thenoyltrifluoroacetone or benzoyltrifluoroacetone. These favorable properties of this extractant for iron(III) was concluded to be due to that it is rather water-soluble but still its tris-iron(III) complex is highly extractable.
