Application of AnaLig resin for 99mTc separation from 100Mo target irradiated in cyclotron

• Dissolution of metallic molybdenum in hydrogen peroxide.
• 99mTc production in cyclotron.
• Technetium adsorption on AnaLig Tc-02 resin.
• Technetium separation from access of molybdenum.

The purpose of this study was the development of procedure for molybdenum metallic target processing after its irradiation in a cyclotron. As a first step the dissolution of molybdenum in various physical forms was investigated. The concentrations of NaOH and (NH4)2CO3 allowing the highest sorption of Tc on AnaLig Tc-02 resin had been found. Based on these results the sintered irradiated Mo pellet was processed. The radionuclidic and radiochemical purities of separated Tc product were evaluated.
