PB - Zielona Góra: Oficyna Wydawnicza Uniwersytetu Zielonogórskiego N2 - The aim of the study was to determine the effect of UV exposure time on the change in concentration of PAHs in industrial wastewater. The study was conducted with the use of coking wastewater collected from the outflow of biological wastewater treatment factory. Ultraviolet irradiation treatment plant was carried out using a variable exposure time: 30, 60 and 90 seconds. Quantification of PAHs was performed by liquid chromatography. N2 - Determined fluoranthene, benzo(j)fluoranthene, benzo(b)fluoranthene, benzo(k)fluoranthene. During exposure to ultraviolet light water treatment decreases in concentrations of PAHs. PAH removal efficiency was in the range from 45 to 62% for the total amount of these compounds, while for the individual is in the range from 17 to 67%. Percentage of degradation depended on the exposure time and the connection rings in the hydrocarbon molecule.
