The increasing order of ion-exchange selectivity for tervalent metal ions: Al<SUP>3+</SUP><<Ga<SUP>3+</SUP>≤Yb<SUP>3+</SUP><Fe<SUP>3+</SUP><La<SUP>3+</SUP><In<SUP>3+</SUP>, was established in 1 mol dm<SUP>−3</SUP> nitric acid solution on a crystalline antimonic(V) acid (C-SbA) cation exchanger. Strong correlation was found between the selectivity and the effective ionic radii of these ions. Large separation factors for neighboring ions were obtained, as compared with the commercial ion exchange resin. An effective separation of aluminium(III)-iron(III) ion pairs and a group separation of garium(III) and ytterbium(III) ions from lanthanum(III) ion were performed by using a relatively small C-SbA column (4 cm× 0.4 cm i.d.).
