摘要: Interphase distribution of La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, and Y between aqueous HCl solutions carbamoylmethylphosphine oxides in the presence binary extractants, quaternary ammonium dinonylnaphthalenesulfonates, has been studied. It shown that efficiency extraction rare earth elements(III) (REE) with increases considerably extractant organic phase. The stoichiometry extracted complexes determined, effect cation nature extractant, solvent, structure oxides, concentration phase on REE(III) recovery into considered.
