Determination of Volatile Compounds of Fission-Product Iodine

Organic iodides, presumably derived from interaction between fission-product iodine and process solvent, were detected and identified by gas chromatography in the exhaust air from the Purex process at the Savannah River Plant. Three of ten peaks obtained were tentatively identified as alkyl iodides by the behavior of the detected compounds and the relative response of an electron absorption detector vs a flame ionization detector.
