Separation of 47Sc produced from natCa(n, γ) reaction for potential medical applications by a synthesized raspberry‐like structure of metal‐organic framework material

This work aimed for the synthesis of a novel metal organic framework through a facile and gamma‐irradiation process to be applied for the separation of scandium‐47 as theranostic radioisotope from the irradiated calcium target. Polyacrylonitrile‐cupric oxide nanocomposite structure (as metal organic framework) was successfully synthesized and characterized. The optimized conditions (such as monomer concentration, weight of cupric oxide nanoparticles and gamma‐dose) for the synthesis of polyacrylonitrile‐cupric oxide were identified. The newly synthesized resin was used to study the separation of micro amounts of scandium‐47 from gram amounts of the irradiated calcium carbonate by batch equilibration and column studies. Preliminary study demonstrated that the Kd values of scandium(III) ions are little higher than that of calcium(II) ions. The elution yield of scandium‐47(III) was found to be 61±2 %. Future work will be done to improve this yield for nuclear medicine applications.
