Description

Anion-exchange behavior of Nb, Ta and Pa in HF/HNO3 media was investigated in order to find suitable experimental conditions for the study of the Db fluoride complex formation. We measured Kd values of those elements on strong basic anion exchangers in the wide range of the fluoride ion concentration, 1 x 10-6 M < [F-] < 2x10-2 M. We discuss the formation of anionic fluoride complexes of the elements on the basis of the variation of the Kd value against [F-] and [NO3-]. Based on these results together with the measurement of the equilibrium time, we propose rapid online experimental condition for the study of the Db fluoride. (author)
