MoO4
2- ions were sorbed in calcined hydrotalcite contained in a column. It was found that 98% of 99mTc
formed by 99Mo decay was eluted through the column in the form of pertechnetate. The content of
radionuclides was determined by γ-spectrometry, and natural molybdenum was measured by neutron
activation analysis. Solids were characterized by thermal analysis, X-ray diffraction, and infrared
spectroscopy. Through batch experiments, the hydrotalcite capacity toward molybdate ions (1.12 × 10-3
M) was found to be 3.2 mequiv g-1. It was found that the high molybdate adsorbing capacity of calcined
hydrotalcite could be utilized in designing a 99mTc generator made with low specific activity 99Mo-molybdate
samples.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
