- Abstract
We prepared three types of Al2O3 with different surface structures and investigated 99Mo-adsorption/99mTc-elution properties using [99Mo]MoO3 that was irradiated in the Kyoto University Research Reactor. Al2O3 adsorbed [99Mo]molybdate ions in solutions at different pH; the lower was the pH, the higher was the Mo-adsorption capacity of Al2O3. The 99mTc-elution properties of molybdate ion adsorbed Al2O3 were elucidated by flowing saline. Consequently, it was suggested that 99Mo-adsorption/desorption properties are affected by the specific surface of Al2O3 and 99mTc-elution properties are affected by the crystal structure of Al2O3.
