Poly zirconium chloride (PZC) as an efficient adsorbent for 99 MO

Abstract

This radionuclide is almost exclusively produced from the decay of its parent 99Mo. 99mTc is the<br />most available and important nuclide used as a diagnostic agent in nuclear medicine. To develop a<br />newly practical 99mTc generator using ( n,y ) 99Mo, an inorganic polymer adsorbent has been<br />developed framed with oxygen-zirconium-chlorine bonds with a high adsorption of Mo, The<br />polyzirconium adsorbent was named PZC ( poly zirconium chloride) which made clear that PZC<br />has an ability and high performance as a practical adsorbent for 99mTc generator using ( n, y)<br />99Mo. The amount of 99Mo adsorbed to PZC reached about 250mg/g PZC. 99mTc was eluted<br />with a small volume of saline solution in the yield of about 76.43 %. The breakthrough of 99Mo<br />in the elution of 99mTc was less than 0.015%.
