Description
Adsorption of carrier-free radiotracers 181W and 93mMo produced in the 181Ta(p, n) and natNb(p, n) reactions, respectively, on anion-exchange resin was studied in mixed solution of HF and HNO3 in a concentration range of 10-4-10-1 M HF/0.1 M HNO3. Distribution coefficients (Kd) of 181W and 93mMo at 70 deg C showed the V-shaped variation with the minimum at around 10-1 M HF/0.1 M HNO3, although variation of the Kd values for 93mMo was quite small compared with that for 181W. Formation of oxofluoro complexes for W and Mo is briefly discussed. (author)
