Research Abstract |
In order to elucidate relevant chemical species of Rf by means of reversed-phase extraction chromatography with 2-thenoyltrifluoroacetone (TTA) as a stationary phase, we measured the equilibration time and distribution ratios in extraction by batch method experiments with carrier-free radiotracers of Zr and Hf on TTA-resin in the HF/HNO3 solutions and optimized an appropriate experimental condition for Rf. An online experiment has been also performed for the reversed-phase chromatographic behaviors of Zr and Hf on the TTA resin to simulate the Rf experiments. The elution curves from columns with the resin in the on-line experiment using Zr and Hf short-lived isotopes were obtained to show the effective adsorption with TTA although the equilibrium has not been attained, yet. The Rf atoms appears to be adsorbed to TTA in the on-line experiment with Rf, but the analysis is still on the way to deriving conclusive results.
