Abstract
The elution chromatographic separation of magnesium isotopes was investigated by chemical ion exchange with the synthesized 1,7-dioxa-4,10,13-triazacyclopentadecane-4,10,13-trimerrifield peptide resin [N3O2·3M]. The capacity of novel N3O2 azacrown ion exchanger was 0.21 meq/g dry resin. The heavier isotopes of magnesium concentrated in the resin phase, while the lighter isotopes are enriched in the solution phase. The glass ion exchange column used in our experiment was 30 cm long with inner diameter of 0.2 cm, and the 2.0M NH4Cl solution was used as an eluent. The separation factors of 24Mg-25Mg, 25Mg-26Mg, and 24Mg-26Mg were 1.030, 1.009, and 1.027, respectively.
