The distribution of a monovalent simple anion, Y-, or of a monovalent metal complex anion, ?\4X,+1-, between an aqueous solution of the supporting electroyte CX and a waterimmiscible solution of an alkylammonium salt E has been described considering the presence in the organic phase of the homopolymers (E), and of the heteropolymers (RX),(RY),. A set of equations has been derived that show the dependence of the experimental distribution data on the concentration of the alkylammonium salt and the extracted anion. A successful reinterpretation of the data existing in the literature on the distribution of U02(NO3)2 between aqueous nitrate solution and alkylammonium nitrate solutions has been carried out. The presence of a mixed tetramer and of monomer terms seems to fit the experimental data.
