Surface modification of acid-functionalized mesoporous gamma-alumina for non-fission < sup > 99 < /sup > Mo/ < sup > 99m < /sup > Tc generator

Appl Radiat Isot. 2022 Jun 21;187:110342. doi: 10.1016/j.apradiso.2022.110342. Online ahead of print.ABSTRACTMesoporous gamma-alumina (MGA) was synthesized for neutron-activated 99Mo adsorbent. Acid functionalization of the MGA was carried out to enhance the Mo adsorption capacity and the 99Mo breakthrough profile. The acid-treated MGA has a more positive particle charge, rougher surface, smaller particle and pore size, larger surface area, and wider pore distance. The acid-treated MGA has a Mo adsorption capacity of 82.8 ± 6.3 mg Mo/g and resulted in 99mTc eluate with the 99Mo breakthrough at the acceptable level.PMID:35759956 | DOI:10.1016/j.apradiso.2022.110342
