Laboratory Set for Chromatographic Isolation of Re-186 Carrier without Irradiated Tungsten Targets

摘要

A laboratory setup has been developed for the isolation of rhenium radioisotopes from an irradiated tungsten target using extraction chromatography. The operation of the setup was tested using a target made of metallic tungsten of natural isotopic composition, irradiated with deuterons at the U-150 cyclotron of the Kurchatov Institute. The possibility of complete separation of rhenium from large amounts (hundreds of milligrams) of tungsten has been shown. During separation, rhenium is concentrated in a minimum volume (5 mL) of the final solution, providing a high specific activity required for further experiments to create a radiopharmaceutical.
