Mesoporous gamma-alumina (MGA) was synthesized for neutron-activated Mo adsorbent. Acid functionalization of the MGA was carried out to enhance the Mo adsorption capacity and the Mo 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 Tc eluate with the Mo breakthrough at the acceptable level.
介孔γ-氧化铝（MGA）被合成用于中子活化 Mo 吸附剂。对 MGA 进行酸功能化处理以增强 Mo 吸附能力和 Mo 穿透曲线。酸处理的 MGA 具有更正的颗粒电荷、更粗糙的表面、更小的颗粒和孔径、更大的表面积和更宽的孔距。酸处理的 MGA 的 Mo 吸附容量为 82.8±6.3mg Mo/g，并且产生 Tc 洗脱液，其中 Mo 穿透达到可接受的水平。
