Separation of molybdenum and technetium on DI-2-ethylhexylphosphoric acid (D-2-EHPA)-kieselguhr.
The distribution ratio of Mo(VI) and Tc(VII) in different acid media on D-2-EHPA-kieselguhr was studied in batch experiments. From these data a separation procedure for Mo-Tc is proposed, which consists in the selective elution of Tc(VII) and Mo(VI) by reverse-phase partition chromatography. The D-2-EHPA-kieselguhr column can also be used as a solid phase for a(99m)Tc generator.
