We report on new and much more precise cation-exchange data of element 104, rutherfordium (Rf), in the fluoride ion concentration [F-] range of 5.29 × 10-5-1.04 × 10-3 M. The result based on one-atom-at-a-time chemistry clearly demonstrates that the distribution coefficients (Kd) decrease with increasing [F-], suggesting successive fluoride complexation of Rf. The complexation of Rf is briefly discussed in terms of fully relativistic density functional calculation theory.
