2015, Akadmiai Kiad, Budapest, Hungary. The extraction behavior of the Rf homologs, Zr and Hf, has been studied in HCl, HNO3, and H2SO4 media using TEVA (a trioctyl and tridecyl methyl ammonium-based resin) and UTEVA (a diamyl amylphosphonate-based resin). All six systems were considered for the future chemical characterization of Rf. Batch uptake studies were first performed to determine which systems could separate Zr and Hf and these results were used to determine what acid concentration range to focus on for the column studies. The batch uptake studies showed that UTEVA separates Zr and Hf in all media, while the intergroup separation was only observed in HCl media with TEVA. Both HCl systems showed viability for potential extraction chromatographic studies of Rf.
