Ultraviolet irradiation of aqueous solutions of iodide/iodate ion containing low molecular weight organic acids generates volatile iodine species that are amenable to detection by atomic spectrometry. In the presence of formic, acetic or propionic acids, photo-chemical generation results in the formation of HI, methyl- and ethyl-iodide respectively, the latter two products being directly identified by gas chromatography-mass spectrometry. Deuterium and C-13-labeled reagents were employed to elucidate the provenance of the alkyl group. Use of (CH3)-C-13-COOH produced (CH3)-C-13-I; deuterated acetic acid (D3C-COOD) resulted in the formation of CD3-I. These observations indicate direct transfer of the alkyl group from the carboxylic acid to iodide, consistent with the suggestion that the mechanism of synthesis involves radical induced reactions.
