Abstract

Generator columns based on Dowex 1X8 anion exchange resin and TEVA extraction chromatography resin with 0.005 M H₂Ox + 0.065 M HCl eluent were compared. The behavior of ⁴⁴Ti and ⁴⁴Sc on the resins is explained by the corresponding fractions of anionic species of Ti^IV and Sc^III in solutions of oxalic and hydrochloric acids mixtures. A laboratory generator based on TEVA with 0.005 M H₂Ox + 0.065 M HCl eluent allowed to obtain over 96% ⁴⁴Sc in 3 ml of eluent with a ⁴⁴Ti breakthrough of no more than 5 × 10⁻⁵%.
