Dw. Kim et al., SEPARATION OF LITHIUM ISOTOPE BY AZACROWN TETRAMERRIFIELD PEPTIDE-RESIN, Journal of radioanalytical and nuclear chemistry, 232(1-2), 1998, pp. 257-259
A study on the separation of lithium isotope was carried out with N4O
azacrown ion exchange resin. The lighter Li-6 isotope concentrated in
the solution phase, while the heavier Li-7 isotope is enriched in the
resin phase. Upon column chromatography (0.3 cm I.D.x15.5 cm height) u
sing 0.5M NH4Cl as an eluent, single separation factor, alpha=1.00127
was obtained.
