In aqueous solutions CO/sub 2/ and bicarbonate react with negatively charged polarons (H/sub 2/O)-- formed by the gamma irradiation of water, leading to formation of the carboxyl radical ion. In the presence of organic solutes, the carboxyl radical ion may add on to other free radicals, e.g., those formed by the action of radiation-produced OH radicals on organic solutes, to give the corresponding carboxylic acids. Using C/sup 14/ labeled carbon dioxide or bicarbonate, this process could provide a method for the production of carboxylic acids labeled in the carboxyl group. In neutral solutions two reducing species, i.e., negative polarons and primarily formed H atoms, were shown to be present in irradiated water; their reactions with various solutes were studied. All irradiations were carried out with Co/sup 60/ gamma rays. For irradiation of aqueous solutions in the presence and absence of different gases (O/sub 2/, CO/ sub 2/, N/sub 2/O) standard irradiation techniques were used. Analysis of the gaseous irradiation products was carried out by means of the mass-spectrometer. Other irradiation products were determined spectrophotometrically or by radioactive tracer techniques.
