| Abstract: | Distribution coefficients of 18 elements in the systems: amphoteric resin Retardion 11A8-NH4Cl2 (NH4Cl+NH3) and (NH4Cl+HCl) were measured by batch equilibration technique with the use of radioactive tracers. On the basis of these data ageneral qualitative interpretation of ion exchange behaviour of inorganic ions on Retardion 11A8 in dependence on pH and composition of aqueous phase is given. The possibility of achieving useful radiochemical separations using Retardion 11A8 columns and exploiting both cation and anion exchange functions of the resin is demonstrated. |
