The yield of photolysis depends on the irradiation intensity, pH and temperature. In the waters there is a natural organic matter, which components can both inhibit and facilitate the process of oxidation of PAHs. Aromatic hydrocarbons under the influence of light and oxygen are easily photochemical reactions to form derivatives, which identification is not exactly recognized.}, abstract={The aim of the study was to evaluate degradability of low molecular weight PAHs (3 - and 4 - ring compounds) when exposed to ultraviolet radiation. Photolysis studies conducted using an aqueous solution containing a standard reference mixture of PAHs. Analyzed hydrocarbons such as acenaphthene, fluorene, phenanthrene, anthracene, fluoranthene, pyrene, benzo(a)anthracene and chrysene using a system comprising a high performance liquid chromatography coupled with fluorescence detector.}, abstract={The irradiation with ultraviolet rays was carried out in solutions of variable exposure time of 1.5; 3.0 and 5.0 minutes. These tests were carried out at different pH reaction environment. The efficiency of removal of PAH ranged from 23 to 48% of the total content of these compounds. Hydrocarbon 3 - and 4- ring is properly in the range of 0 to 23% and from 59 to 73%. The efficciency of degradation depended on the exposure time and the pH of thesolution.}, type={artykuł}, title={Fotoliza WWA w roztworach wodnych = Photolysis of PAHs in water solutions}, keywords={WWA, HPLC, fotodegradacja, pH, PAHs, photodegradation}, }
