“…The calculated SBET was 237.65 m 2 /g, similar with most alumina SBET which is ranging from 200-450 m 2 /g (Chakravarty et al, 2013;Saptiama et al, 2017Saptiama et al, , 2019. Even though the surface area is an important parameter for the adsorption process, the other parameter, for instance, crystal phase and acidity, might also play an important role (Sulaiman et al, 2018). The synthesized SS-alumina was packed in a glass column with frit as seen in Figure 2.…”

Technetium-99m (99mTc), a daughter radionuclide of molybdenum-99 (99Mo), is the most widely used radiodiagnostic agent due to its ideal characteristics. The separation of this radionuclide from 99Mo is commonly performed using alumina. However, a new production method of this radionuclide, which employs a low specific activity 99Mo, makes alumina no longer suitable as separation material. This study aims to develop novel alumina using a facile solid-state reaction for 99Mo/99mTc generator system. The SS-alumina was synthesized from aluminium nitrate nonahydrate and ammonium bicarbonate without solvent. The resulted SS-alumina was then analyzed by FTIR and BET method. 99Mo adsorption and 99mTc releasing study on a series of pH were also performed. FTIR study revealed that the resulting material was Al2O3 with a surface area of 237.65 m2/g. The adsorption capacity, 99mTc yield, 99Mo breakthrough, and alumina breakthrough were 76.06 mg Mo/g alumina, 80.31%, 56.5 µCi/mCi 99mTc, and less than 5 mg/mL, respectively. The elution profile shows a high activity of 99mTc in 2nd and 3rd fraction. It is concluded that the SS-alumina shows good performance as adsorbent material for separation of a 99Mo/99mTc and further work is now underway.

“…This might increase the affinity of 99 Mo species to bind alumina. The higher the pH value, the lower the adsorption capacity of alumina (Sulaiman et al, 2018). Table 1 also shows that in pH 4, the column can release the eluate, while in pH 5 and 6 cannot.…”
