Disscussion is of a number of experiments done during this period to determine the degree to which Iodine, added in the zero oxidation state to a simulated dissover solution, can be removed by sparging. The effects of variables such as temperature, spargant and spargant flow rate, acidity and UNH concentration of the rate of Iodine removal was studied. As expected, Iodine removal increawed as the temperature increased. The use of an inert spargant such as nitrogen appears to have a slight advantage over oxygen-containing spargants. Results of the experiments are given in data tables. Concentration of Uranium seems to have little effect on the ultimate removal of Iodine, at least for concentrations studied. However, the initial rate of removal was considerably greater for the high UNH concentration. Experience in the operation of the radioactive Iodine production unit at Oak Ridge has shown that the presence of very small amounts of mercury in dissolver solution renders the Iodine very difficult to remove by sparging.
