The separation of zirconium isotopes has been studied by means of cation-exchange chromatography using zirconium-triammonium citrate and zirconium-diammonium citrate systems. Small but appreciable isotope fractionations were observed in both systems. In the former system, the lighest isotope 90Zr was enriched at the rear part of the zirconium band, while in the latter case 90Zr was depleted at the rear part. The elemental separation coefficients, ε, were around 1 · 10-6 for the zirconium-triammonium citrate systems and around -0,5 · 10-6 for the zirconium-diammonium citrate systems. The isotope effect is discussed in terms of the hydrolysis of the zirconium species.
