Preparation of a New Column Stuffing for ~(99)Mo-~(99)Tc~m Generator

A new polyinorganic column stuffing (Polyinorganic Zirconium Compound; PZC) for 99Mo-99Tcm generator is synthesized with both ZrCl4 and isopropyl alcohol in proper reaction condition. It is analyzed and identified too. The absorption characteristics of Mo to PZC are investigated by non-radioactive Mo using static absorption test. The elution performance of the new 99Mo-99Tcm generator is studied by radioactive "Mo and elution profile of 99Tcm from PZC 99Mo-99Tcm generator is examined. The elution efficiency and radiochemical purity are also abserved. The results show that the absorption capacity of Mo to PZC is up to 318. 0 mg/g. 88Tcm is easily eluted with 3 mL of saline solution in the yield of 64. 90%.
