Preparation of 177Lu Using Vacuum Sublimation Technology

Abstract A simple sublimation technology for the lutetium and ytterbium separation was proposed, which already at the stage of preliminary experiments showed effectiveness: (a) the completeness of Yb separation resulted in short-term thermal annealing is at least 98%, the distilled product is completely free from 177 Lu, no additional preparation of ytterbium for repeated irradiation is required ; (b) traditional ion-exchange chromatography can be used for the final purification of 177 Lu from ytterbium.
