摘要:
Lead-203 was produced by proton bombardment of natural thallium target. For producing Pb-203, Tl-nat was electroplated on copper backing as target and was bombarded by energetic proton beam. After bombardment, the target was dissolved in 1 M HNO3. Ion exchange, solvent extraction, and nanomagnetic ion-imprinted polymer methods were used for separating Pb-203 from thallium. The separation efficiency of these methods was studied. gamma-Ray spectroscopy was applied for evaluating Pb-203 and others radionuclides. The separation efficiency was determined from the gamma-ray spectra. The separation efficiency of the methods using ion exchange, solvent extraction, and nanomagnetic ion-imprinted adsorbent was 98, 99.3, and 96.4%, respectively.
