摘要：

The Eu-153/151 isotope separation factor (q) for the Eu(II)/Eu(III) chemical exchange in the liquid-liquid extraction system, containing Eu(III) in di(2-ethylhexyl)phosphoric acid (HDEHP) and Eu(II) in water acidified with hydrochloric acid, was found to be 0.9993 +/- 0.0002 (2sigma) for the single stage. Some theoretical aspects of separation of the Eu isotopes are discussed. The decisive role of the electron exchange reaction adn complexation by the counter-ion in the aqueous phase is emphasized.
