| Abstract | The extraction of U(VI), Ce(IV), La(III), Nd(III), Sm(III), and Y(III) from an aqueous solution of Na2CO3 (0.25 mol/L) resulting from oxidative dissolution of U(IV) in the presence of H2O2 into a solution of methyltrioctylammonium carbonate (0.25 mol/L) in toluene. It was found that βU(VI)/Ln(III) values vary from ~8 to 3290 as the O : W ratio changes from 2 : 1 to 10 : 1, while βU(VI)/Ce(IV) varies from ~1.5 to 10, which allows for the extraction separation of U(VI) from Ce(IV) in a 8- to 10-stage counter-current extraction cascade and from Ln(III) in 2- to 3-stage cascade under the same conditions. |
