Abstract

A crown-ether based extraction chromatography resin, Eichrom Pb, has been characterized for separations of the flerovium (Fl) pseudo-homolog Hg. Previous results on the batch uptake of Pb(II) and Sn(IV) are compared with newly investigated Hg(II) in HCl matrices. It was determined that all three elements can be strongly retained by the resin at different HCl concentrations. To assess the feasibility for performing an experiment on the chemical properties of Fl using this resin the extraction kinetics were studied. A separation method for the isolation of the homologs Pb(II) and Sn(IV) and pseudo-homolog Hg(II) has been established using 2 mL pre-packed Pb resin columns under vacuum flow.
