Abstract: | The effects of temperature, heating-time, concentration of HNO3 and γ-ray irradiation on the valence states of iodine in a simulated fuel solution of a medical isotope production reactor
(MIPR) were investigated. About 83% of I− was oxidized to IO3
− and 10% of I− was oxidized to I2 in uranyl nitrate solution after heating at 70 °C for 6 hours. Heating and existence of oxidant, U and ionizing radiation
accelerate the oxidation process of iodine, and results in most of the iodine being produced in high oxidation states such
as in IO3
− and IO4
−. The results indicate that the production of 131I by MIPR can be carried out by extraction of iodine in high oxidation states from the fuel solution. |
