We investigated anion-exchange behavior of Nb, Ta and Pa in HF/HNO media to find suitable experimental conditions for the study of the Db fluoride complex formation. We measured Kd values of Nb, Ta and Pa on strong basic anion exchangers in the wide range of the fluoride ion concentration, 1

M, in order to in detail investigate anionic fluoride complex formation of those elements. We have used tracer concentrations of isotopes of 
Nb, 
Ta and 
Pa in the experiments. Variation of the Kd values as a function of [NO
] was also studied. As a result, we observed an apparent difference in the adsorption behavior of the homologues. Based on these results together with the measurement of the equilibrium time, we propose rapid online experimental condition for the study of Db fluoride.
