In Mo/ Tc generator, a chromatography column system with Mo adsorbent as filler usually used to produce hospitals. However, it still challenging find high-performance adsorbents adsorption . We have synthesized both ordered and disordered mesoporous alumina compared their performance s These materials were prepared via soft-templated method using triblock copolymer template followed by air calcin ation at 400 ° C. T he amount nitric acid (HNO 3 ) drying time adjusted systematically synthesize alumina. The obtained characterized low-and wide-angle X -ray diffractions (XRD) nitrogen adsorption-desorption, ther mo gravimetric analysis (TGA), scanning electron microscop y (SEM), transmission (TEM). capacit ies these evaluated batch method. experimental results show that has higher capacity 72.06 mg (Mo) g -1 than 50.12 indicate excellent potential o rdered generator
