Title
(EN) SYSTEM AND METHOD FOR METALLIC ISOTOPE SEPARATION BY A COMBINED THERMAL-VACUUM DISTILLATION PROCESS

Abstract
(EN)
A process for the separation of 99mTc from molybdenum targets is described. The method for separation of 99mTc isotope from molybdenum targets includes: i) providing an initial multicomponent mixture of elements, the mixture containing 99mTc; 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 containing 99mTc; iv) condensing the vaporized compound containing 99mTc to form a reaction product; v) adding a base to the condensed reaction product to dissolve the 99mTc containing reaction product to form sodium pertechnetate (Na 99mTcO4); and vii) purifying the crude solution of sodium pertechnetate Na99mTc04 using column chromatography to provide the 99mTc isotope as a radiochemical compound.

L'invention concerne un procédé pour la séparation de 99mTc à partir de cibles en molybdène. Le procédé pour la séparation d'isotope 99mTc à partir de cibles en molybdène comprend : i) l'utilisation d'un mélange initial d'éléments à plusieurs constituants, le mélange contenant du 99mTc; ii) la dissolution du mélange d'éléments à plusieurs constituants avec un agent oxydant pour oxyder le mélange d'éléments; iii) le chauffage du mélange d'éléments à une température suffisamment élevée pour sublimer un composé vaporisé contenant du 99mTc; iv) la condensation du composé vaporisé contenant du 99mTc pour former un produit réactionnel; v) l'ajout d'une base au produit réactionnel condensé pour dissoudre le produit réactionnel contenant du 99mTc pour former du pertechnétate de sodium (Na99mTcO4); et vii) la purification de la solution brute de pertechnétate de sodium Na99mTcO4 à l'aide de la chromatographie sur colonne pour obtenir l'isotope 99mTc en tant que composé radiochimique.
