Abstract
Elution chromatographic separation of lithium isotopes was carried out with aminobenzo-15-crown-5 bonded merrifield resin. This resin have a capacity of 0.24 meq/g dry resin. By column chromatography using 1.0M NH4Cl solution as an eluent a single separation factor 1.026 was obtained from the elutio n curve and isotope ratios according to the Glueckauf theory. The heavier i sotope, Li-7 was concentrated in the resin phase, while the lighter isotope , Li-6 enriched in the solution phase.
