Rapid separation of radiogallium from Zn and Cu targets using anion exchange technique

A simple, non-destructive and rapid radiochemical separation of radiogallium from Zn and Cu targets by ion-exchange chromatography using Amberlyst 21b was studied. The separation yield was high, while the chemical impurity in the separated radiogallium (inactive Zn or Cu) was low (< 0.4 mu g). The final product was obtained in the form of gallium citrate in a single step method technique that avoided the time consumption and corrosive evaporation.
