Abstract :
A 99mTc generator has been prepared using an inorganic polymer adsorbent newly developed for low specific activity 99Mo. The adsorbent (PZC) was synthesized from zirconium chloride and isopropyl alcohol on heating. To adsorb 99Mo, PZC was added to the solution of 99Mo prepared from neutron-irradiated natural MoO3. The amount of 99Mo (Mo) adsorbed to PZC reached about 200 mg/g-PZC. Technetium-99m was eluted with a small volume of saline solution in the yield of about 80%. The breakthrough of 99Mo was less than 0.5% in good conditions.
