Separation And Purification Of Radioiodine 131I by Means of wet Distillation Method From By-Product of U-235 Fission Produced 99Mo Process

The production of 99Mo from 235U fission also produces radioiodine fraction as by product. The radioiodine fraction can be expected to be a complement for radioiodine 131I produced by neutron activation on TeO2 target. Separation and purification were therefore carried out from radioiodine fraction obtained from production process of 99Mo fission product. The radioiodine 131I fraction was separated and purified by means of wet distillation method that is often used for separating 131I from post-neutron activated TeO2. The quality control of the resulting products indicates that the resulting radioiodine 131I solution was suitable to be used for labelling or synthesis of 131I labelled compounds. Although the efficiencies of separation and purification were found to be low ranging between 25 to 37%, the result of the presented experiment generally affirm the consideration to exploit the 131I fission product for labelling or synthesis of 131I radiopharmaceuticals.
