    Notes: Summary The dependence of the chloride distribution coefficient on the co-ion of solutions of different alkali fluorides, MF, up to 11M is tested on the strongly basic anion-exchange resin AG1-X10. Under the same experimental conditions the distribution coefficient decreases in the following order for M+: Na+〉K+〉Rb+〉Cs+. This can be explained by the different co-ion-chloride interactions. The consequence of this interaction for a chromatographic separation of chloride is shown with 5M KF and CsF solutions, used as eluants. Depending on the fluoride concentration, the distribution coefficient passes through a minimum value to increase again at higher electrolyte concentration. The non-exchange electrolyte in the resin phase is responsible for this effect. In addition, the bromide and the iodide distribution coefficients up to 10M KF solutions are determined. One results is that the selectivity coefficient between halide ions increases at higher electrolyte concentrations.

    Description / Table of Contents: Chlorine Isotope Separation in a Heterogeneous Electrolyte System Dependence on the Concentration and the Counter Ion of a Fluoride SolutionIn a heterogeneous electrolyte system of a strongly basic anion exchanger and a concentrated fluoride solution the dependence of the chlorine isotope separation on the concentration and the counter ion of the fluoride solution is determined by chromatographic experiments. The results show the greatest separation effect of the chlorine isotopes so far achieved, using ion exchange reactions. 37Cl- is enriched in the solution phase, whereas 35Cl- is enriched in the ion exchanger. With increasing fluoride concentration the isotope separation effect decreases. The strong dependence of the isotope separation on the counter ion of the fluoride solution is shown using CsF and KF respectively.
    Notes: Im heterogenen Elektrolytsystem stark basischer Anionenaustauscher/konzentrierte Fluoridlösung wird die Abhängigkeit der Chlorisotopenseparation von Konzentration und Gegenion des Fremdelektrolyten in chromatographischen Versuchen bestimmt. Die Ergebnisse zeigen den bisher größten bekannten Elementartrenneffekt der Chlorisotope bei Ionenaustauschreaktionen, wobei sich das 37Cl- - gegenüber dem 35Cl--Ion in der Lösung des Systems anreichert. Mit steigender Fluoridkonzentration nimmt der Isotopentrenneffekt ab. Am Beispiel einer CsF - gegenüber einer KF - Lösung wird die starke Abhängigkeit der Isotopenseparation vom Gegenion des Fremdelektrolyten aufgezeigt.
