Abstract
A process for the separation ofTc from molybdenum targets is described. The method for separation ofTc isotope from molybdenum targets includes: i) providing an initial multicomponent mixture of elements, the mixture containingTc; ii) dissolving the multicomponent mixture of elements with an oxidizing agent to oxidize the mixture of elements; iii) heating the mixture of elements at a temperature sufficiently high enough to sublimate a vaporized compound containingTc; iv) condensing the vaporized compound containingTc to form a reaction product; v) adding a base to the condensed reaction product to dissolve theTc containing reaction product to form sodium pertechnetate (NaTcO); and vii) purifying the crude solution of sodium pertechnetate NaTc04 using column chromatography to provide theTc isotope as a radiochemical compound.
