An apparatus for the measurement of iodine volatilization from irradiated CSI solutions

grantor: University of TorontoA separate effect flow apparatus was designed and constructed to examine volatile iodine production rates. This system allowed the impacts of pH, dissolved oxygen, mass transfer rate, iodide concentration and the addition of organics to be independently examined. The acquired data set indicated that the apparatus was able to fulfil its mandate of enabling a broad examination of the parameters believed to have the greatest effect on the volatilization of iodine. For 10-5 and 10-4 M buffered CsI solutions, a one order of magnitude rate increase was observed between acidic and basic solutions. Additionally, the introduction of MIBK at fixed pH was found to cause a significant rise in the volatilization rate while decreasing the dissolved oxygen concentration decreased this rate.M.A.Sc
