Summary The ion exchange selectivity of trivalent metal ions has been determined on titanium antimonate cation exchanger prepared by coprecipitation of antimony to titanium at different mole ratios. The selectivity sequence Al3+〈Cr3+〈Ga3+〈In3+〈Fe3+ was found for trivalent metal ions at an initial concentration of 10−4 mol dm−3 in nitric acid media. A high separation factor αGa/Al = KdGa/KdAl, 4.8×103, was observed for the Ga3+−Al3+ pair on titanium antimonate with an antimony to titanium ratio of 0.34. The effective separation of Ga3+ and In3+ from Al3+ was achieved using a 3 cm×0.5 cm i.d. column containing titanium antimonate with an antimony to titanium ratio of 0.34.
