Adsorption of carrier-free radiotracers $$^{181}$$W and $$^{rm 93m}$$Mo produced in the $$^{181}$$Ta($$p$$, $$n$$) and $$^{rm nat}$$Nb($$p$$, $$n$$) reactions, respectively, on anion-exchange resin was studied in mixed solution of HF and HNO$$_{3}$$ in a concentration range of 10$$^{-4}$$ - 10$$^{-1}$$ M HF/0.1 M HNO$$_{3}$$. Distribution coefficients ($$K_{rm d}$$) of $$^{181}$$W and $$^{rm 93m}$$Mo at 70 $$^{circ}$$C showed the V-shaped variation with the minimum at around 10$$^{-1}$$ M HF/0.1 M HNO$$_{3}$$ although variation of the $$K_{rm d}$$ values for $$^{rm 93m}$$Mo was quite small compared with that for $$^{181}$$W. Formation of oxofluoro complexes for W and Mo is briefly discussed.
