This paper examines extractants containing D2EHPA (Eu, Cm, Am, Bk and Cf) and a material containing another class of organophosphorus compound: phosphine oxides OPC. The behavior of the transplutonium and rare-earth elements was examined in aluminum nitrate and nitric acid solutins. The static results are presented for A1(NO/sub 3/)/sub 3/; there are no major differences in behavior with OPC extractant that would enable one to separate them. The dependence of the partition coefficient on the aluminum nitrate concentration is the converse of that found with D2EHPA.
