Abstract

A study on the separation of lithium isotopes was carried out with an ion exchange resin having 1,7,13-trioxa-4,10,16-triazacyclooctadecane (N3O3) as an anchor group. The lighter isotope,6Li concentrated in the resin phase, while the heavier isotope,7Li is enriched in the fluid phase. Upon column chromatography [0.6 cm (I. D.)×20 cm (height)] using 1.0M ammonium chloride solution as an eluent, single separation factor, α, 1.068 (6Li/7Li)resin/(6Li/7Li)solution was obtained by theGlueckauf method from the elution curve and isotope ratios.
