Comparative study of the radiolysis and photolysis of the ethanol solutions of polychlorinebiphenyls

Model solutions of polychlorinebiphenyls, containing 12 congeners in ethanol were irradiated by gamma rays at 14–140 kGy absorption doses, as well as by UV-rays for 2–30 minutes using middle pressure mercury lamp (PRK‑4, λ = 253 ÷ 546 nm.), and the kinetics of the radiolytic PCBs degradation processes was investigated. The PCBs identification was conducted using a Gas Chromatography (Agilent Technologies 7820A).
