Abstract

Cation exchange column chromatography of lithium was carried out to investigate the lithium isotope separation in aqueous ion exchange system. A Pyrex glass column of <TEX>$50cm{\times}6mm$</TEX> inner radius with a water jacket was used as the separation column in experiment. Upon column chromatography using hydrochloric and succinic acid mixtures as an elunent, single separation factor, <TEX>${\alpha}$</TEX>, 1.0068 was obtained. From the experiment, it was found that <TEX>$^6Li$</TEX> was enriched in the resin phase and <TEX>$^7Li$</TEX> in the solution phase.
