Features of Ti<sup>IV</sup> and Sc<sup>III</sup> behavior in oxalic acid solutions affecting the <sup>44</sup>Ti/<sup>44</sup>Sc generating system based on anion exchange resins
Generator columns based on Dowex 1X8 anion exchange resin and TEVA extraction chromatography resin with 0.005 M H<sub>2</sub>Ox + 0.065 M HCl eluent were compared. The behavior of <sup>44</sup>Ti and <sup>44</sup>Sc on the resins is explained by the corresponding fractions of anionic species of Ti<sup>IV</sup> and Sc<sup>III</sup> in solutions of oxalic and hydrochloric acids mixtures. A laboratory generator based on TEVA with 0.005 M H<sub>2</sub>Ox + 0.065 M HCl eluent allowed to obtain over 96
