Description
Radioactive isotopes have been found of valuable applications in different areas such as medicine, industry, agriculture and biology. One of these isotopes is 153 Sm which is obtained by irradiation of natural Sm2O3 in a reactor by a thermal neutron flux of 1014 n.cm-2.sec -1 for 8 hours to get n specific activity of 67-95 mCi/mg. Thc distribution coefficient of 153 Sm and 154,155Eu from different media with different concentrations of HCl and EDTA onto Resorcinol-Formaldehyde as a cation exchanger were studied. The effect of ascorbic acid concentration at 0.001 and 10 M HCl on the distribution coefficient of 153Sm and 155Eu onto the same exchanger was studied. 153Sm was separated by elution chromolithography with 0.4 M EDTA. As a result, the radionuclidic purity of the eluted 153Sm was over 99% and chemical: purity was over 95%
