Abstract

The novel N₄S₂ azacrown ion exchange resin was prepared. The ion exchange capacity of N₄S₂ ion exchanger was 0.34 meq/g dry resin. A study on the separation of lithium isotopes was carried out with N₄S₂ azacrown ion exchange resin. The lighter isotope, ⁶Li is concentrated in the resin phase, while the heavier isotope, ⁷Li is enriched in the solution phase. With column chromatography [0.1 cm (I.D.)x32 cm (height)] using 2.0M NH₄Cl as an eluent, separation factor, a = 1.034 was obtained.
