Published: June 2020

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