Abstract
The kinetics of changes in the concentration of toxic components under γ-irradiation of industrial wastewater from an oil refinery in the presence of nano-γ-Al2O3 has been studied. The concentration of phenols, surfactants, COD and the total content of oil products at various adsorbed dose were monitored. UV - spectrometric studies of irradiated samples in the range of 200-400 nm shows, that increasing the absorbed dose leads to a decrease in UV - absorption (Abs) in the region of 200-210 nm. The mechanism of the observed regularities is discussed, including radiation-chemical processes occurring in the liquid phase, the participation of electron-donor centers in the decomposition of adsorbed molecules and adsorption of radiolysis products on the surface of nano-γ-Al2O3. Keywords: Radiolysis, nano-γ-Al2O3, wastewater, surfactants, oil products, COD.
