Abstract

Al2O3 nanoparticle is effectively used as an adsorbent for the low specific activity of molybdenum-99 (99Mo). The Al2O3 nanoparticle was synthesized by the green synthesis method using Hibiscus rosa-sinensis leaf extract (HRE). The Al2O3 nanoparticle synthesized using 10% of the HRE has a crystallite size of 4.9 nm, a surface area of 254.6 m2/g, a pore size of 9.1 nm, a pore volume of 0.58 cm3/g and has a Mo adsorption capacity of 43.4 ± 6.1 mg Mo/g.
