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.
