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 x 10(-5)-1.04 x 10(-3) M. The result based on one-atom-at-a-time chemistry clearly demonstrates that the distribution coefficients (K-d) 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.
