A separation of Po-209, Bi-207 and Pb-212 using AG 50Wx8 and AG MP 50 cation exchange resins in an HCl medium was developed. A procedure in which Po(IV) elutes first in 0.2 M HCl, followed by Bi(III) in 0.4 M HCl and finally Pb(II) in 2 M HCl was established. The separation using AG 50Wx8 provides a much better elution profile than that of AG MP 50 with no overlap between the elution bands. This separation has the potential to be used as an isotope generator for producing Po-210 from Pb-210.
