Purification of Carrier-Free 47Sc of Biomedical Interest: Selective Separation Study from natCa(n,γ)

Autor: Ahmed M. Shahr El-Din, Hoda E. Rizk, Mohamed F. Attallah

Publikováno v: Separations, Vol 10, Iss 1, p 8 (2022)

47Sc for theranostic medical applications was produced from the neutron activation of a natural calcium target. Liquid–liquid extraction for separation of the 47Sc radioisotope from 47Ca was carried out with the extractant Cyanex 272 ((2,4,4-trimet

Development of purification of no-carrier-added 47Sc of theranostic interest: selective separation study from the natTi(n,p) process

Autor: Hoda E. Rizk, Mohamed M. E. Breky, Mohamed F. Attallah

Publikováno v: Radiochimica Acta. 111:273-282

Scandium-47 is one of the most promising medical radioisotopes, and its production and trace separation make it an attractive candidate for theranostic application. In this study, the production of no-carrier-added (NCA) 47Sc through the natTi(n,p) r
