By means of high-performance liquid chromatography, spectrophotometry, and chemical analysis, it was found that UV absorption of γ-irradiated aqueous solutions of polyols, such as glycerol, inositol, and xylitol, is due to the presence of malonic dialdehyde (MDA) and other β-dicarbonyl radiolytic products in the form of ketols. The contribution of MDA to these spectra is determined by the structure of the initial polyol, the pH of the solvent, and the absorbed dose of irradiation. Mechanisms for the formation of the radiolysis products in question are proposed.
