文摘

A crown-ether-based extraction chromatography resin, Eichrom Pb resin, was characterized for separations of flerovium (Fl) homologs, specifically Pb and Sn. The batch uptake of Pb(II) and Sn(IV) radionuclides was determined from an HCl matrix. Both Pb(II) and Sn(IV) are strongly retained on the resin at different HCl concentrations. The affinity for Pb(II) decreases with increasing HCl concentration while Sn(IV) uptake increases. Extraction kinetics for Pb(II) and Sn(IV) were examined and show suitable uptake on the second time scale. Separation methods for the isolation of individual homologs, Pb(II) and Sn(IV), have been established using 2 mL pre-packed vacuum flow Pb resin columns.
