Abstract

Abstract: In this work, technetium-98 ( 98 Tc) was prepared with high isotopic purity via the nuclear reaction 98 Mo (p, n) 98 Tc for the first time. An enriched 98 Mo metal target formed by spark plasma sintering was bombarded with 9.4 MeV protons in a CS-30 cyclotron. A microgram amount of 98 Tc with 99.18% isotopic purity was separated from the irradiated target by anion exchange chromatography. Additionally, a chemical procedure for recovering the enriched 98 Mo with a 97% recovery rate was developed. Highlights: A microgram of 98 Tc was produced with 99.18% isotopic purity via the nuclear reaction 98 Mo (p, n) 98 Tc for the first time. Radiochemical purification of 98 Tc from the 98 Mo target was carried out by anion exchange chromatography. A recovery procedure for molybdenum with a recovery rate of 97% from the sodium hydroxide effluent fractions was explored.
