Preparation and performance of 99Mo/99mTc chromatographic column generator based on zirconium molybdosilicate

Abstract: Zirconium molybdosilicate (ZrMoSi) gel prepared using 99 Mo radiotracer via peroxo route was used as a base material for 99 Mo/ 99m Tc column generator. The 99m Tc elution yield and 99 Mo breakthrough in the eluate were studied as a function of the pH-value of gel precipitation, gel drying temperature and Zr : Mo : Si molar ratio. Precipitation pH-value of 2, drying temperature of 100 ∘ C and Zr : Mo : Si molar ratio of 0.5 : 0.5 : 1 were found to be the optimum conditions achieving 99m Tc elution yield of 82%… Show more

“…1590 and 3370 cm À1 may be attributed to the bending and stretching vibrations of the adsorbed water molecules. [44][45][46][47] However, on calcination of the combustion products, Fig. 2(d-f), the vibrational peaks due to the organic residues disappeared.…”

“…Tc generator was used for clinical research at Brookhaven medical department, which paved the way for the first utilization of 99 Mo/ 99m Tc generators in clinical investigations at Argonne Cancer Research Hospital in 1961 (Richards, 1965;Lebowitz and Richards, 1974;Atkins, 1975). Later on, through the following seven decades, the idea was developed, and several 99 Mo/ 99m Tc generator structures were established based on the different physical and chemical behaviors of 99 Mo and 99m Tc radionuclides (Allen, 1965;Boyd, 1987;IAEA, 1995IAEA, , 2013bMaoliang, 1997;Osso and Knapp, 2011;Knapp and Baum, 2012;Mostafa et al, 2016).…”

“…Then, the molybdate- 99 Mo matrix is precipitated from its solution as an insoluble gel material. After that, the dried precipitate is packed into a column for 99m Tc elution (Boyd, 1982a(Boyd, , 1982b(Boyd, , 1987(Boyd, , 1997Evans et al, 1987;Moore et al, 1987;El-Kolaly, 1993;IAEA, 1995;Junior et al, 1998;Monroy-Guzman et al, 2003, 2007, 2008Saraswathy et al, 2004;Davarpanah et al, 2009;Mostafa et al, 2016).…”
