Bestimmung sehr kleiner Verteilungskoeffizienten von Cs, Na und Ba zwischen Lösung und KCl-Einkristallen mit Hilfe radioaktiver Isotope

Abstract

Distribution of Cs, Na, and Ba between great monocrystals of KCl and water solution was investigated. Impurity was either labelled by long-lived radioactive isotopes or was activated after growth of the crystals by neutrons in a nuclear reactor. No influence on partition coefficients was caused by using radioactive tracers, e.g. due to raised inclusion of mother liquor. Between impurity concentrations from 3·10−4 to 10−1 in the solution the partition coefficients were nearly constant and about 10−3 for Na, about 10−4 for Cs, and <5·10−5 for Ba in KCl at temperatures of 40° C. If different impurity ions were built in simultaneously, the partition coefficients were independent of composition of solution. In case of Cs in KCl capture of Cs increased with increasing temperature.
