The solvent extraction of iron(III) in nitric acid (1 to 13.2 mol dm<SUP>−3</SUP>) with seven β-diketones into carbon tetrachloride was studied. The extraction curve has a pronounced minimum at from 6 to 7 mol dm<SUP>−3</SUP> acid, and the extracted iron(III) species were assumed to be represented by FeA<I><SUB>a</SUB></I>(NO<SUB>3</SUB>)<SUB>3−<I>a</I></SUB>(HA)<I><SUB>n</SUB></I> (where <I>a</I> and <I>n</I> are from 0 to 3).
