Abstract

The extraction behavior of rutherfordium (Rf) onto trioctylphosphine oxide (TOPO) resin from 2.0 – 7.0 M HCl solutions was studied together with that of the homologues Zr and Hf. The extraction yields of Rf, Zr, and Hf increased with an increase of HCl concentration, and the sequence of their extraction was Zr > Hf ≥ Rf. It is suggested that the stability of the RfCl₄·2(TOPO) complex is lower than that of the corresponding species of the homologues.
