Abstract
The novel NDOE (1,12,15-triaza-3,4:9,10-dibenzo-5,8- dioxacycloheptadecane) ion exchange resin was prepared. The ion exchange capacity of NDOE azacrown ion exchanger was 0.2 meq/g dry resin. A study on the separation of lithium isotopes was carried out with NDOE novel azacrown ion exchange resin. The lighter isotope, 6Li concentrated in the solution phase, while the heavier isotope, 7Li is enriched in the resin phase. By column chromatography (0.1 cm 1.D.x32 cm height) using 2.0M NH4Cl as an eluent, a separation factor, a = 1.0201 was obtained.
