Anion-exchange behavior of the group-5 elements Nb and Ta, and their pseudo homologue Pa in HF and HF/HNO solutions was investigated by a batch method to find suitable conditions for the anion-exchange experiment of element 105 (Dubnium, Db). We determined distribution coefficients of those elements on the anion-exchange resin as a function of the F
and NO concentrations. Clearly different anion-exchange behavior was observed among these elements. Based on the results, we discuss the fluoro-complex formation of each element and suggest experimental conditions for the study of fluoride complexation of Db.
