A simple and sensitive separation technique of 99Mo and 99mTc from their equilibrium mixture

Abstract

The present work describes a simple and inexpensive separation method of 99 Mo from the equilib- rium mixture. The liquid-liquid extraction technique has been employed to separate 99 Mo and 99m Tc using tri- isooctylamine (TIOA). The 99 Mo and 99m Tc were quanti- tatively separated out in 2 M TIOA with tripled distilled water; 99m Tc was back extracted from TIOA organic phase to aqueous phase by 0.1 M DTPA. The species information or indirect speciation of molybdenum was also established by the extraction profile of the molybdenum.
