Abstract
Perfluorinated organic compounds belong to the class of especially persistent anthropogenic pollutants of natural environment. They are practically not biodegraded, and among advanced oxidation/reduc-tion processes employed for their decomposition, as the most efficient, so far, was reported sonolysis. In this work the radiolytic decomposition of a commonly occurring perfluorooctanoic acid (PFOA) was examined as result of treatment with γ radiation and electron beam. It was found that among the radicals produced from the radiolysis of water, in diluted aqueous PFOA solutions, the fastest reaction takes place with hydrogen radicals, for which reaction rate-constant with PFOA was determined using the pulse radiolysis with spectrophotometric detection as 9.0 x 107 M-1s-1
