The isotope separation coefficient of lithium electromigration through a cation exchange membrane is determined at 6, 11, 20 and 40 °C . It is found that this coefficient increases with temperature while the slope of the isotope distribution in the band decreases with increasing temperature. These tendencies are opposite to those usually observed in ion exchange chromatography.

Chloride Salts

Mixtures of the radionuclides Na22 and Na24, as the chloride salts, have been partially separated by chromatographic methods. A column 102 cm. in length containing the cation exchange resin Dowex 50 was used. The eluant was 0.7 M hydrochloric acid. Na22 is held more strongly by the resin than is Na24. The most effective separations were obtained at 25 °C and 5.5 °C.; experiments at 48 °C and 68 °C showed much smaller isotope effects.
