Development of mesoporous γ-alumina from aluminium foil waste for 99 Mo/ 99m Tc generator

Mesoporous alumina (MA) has been produced from aluminium foil waste, and its performance as a sorbent in a 99Mo/99mTc generator has been evaluated. The resulting MA demonstrated excellent properties with the specific surface area of 209.8 m2 g−1 and Mo adsorption capacity of 60.2 ± 1.5 mg g−1. It was able to release 99mTc with a high yield percentage and to comply with the required standard. Our successful effort on the synthesis of aluminium foil based alumina sorbent has opened the possibility of further work on the development of waste-based alumina for separation.
