Summary
A solvent extraction method for the separation of technethim and molybdenum is outlined. After irradiation of MoO3 and dissolution in sodium hydroxide, the short-lived 99mTc isotope is extracted from 1 M hydrochloric acid into a solution of tri-iso-octylamirie in 1,2-dichloroethane. The percentage of 99Mo in organic phase is less than 0.5%.
Zusammenfassung
Eine Extraktionsmethode zur Trennung von Technetium und Molybdän wird beschrieben. Hierbei wird nach Neutronenbestrahlung von MoO3 und Auflösung in Natronlauge das kurzlebige 99mTc-Isotop aus 1 m salzsaurer Lösung in eine Tri-iso-octylaminlösung in 1,2-Dichloräthan extrahiert. Weniger als 0,5% 99Mo finden sich in der organischen Phase.
