A dose 7.4 mL of dihydrogen dioxide in the amount of and 14.8 mL/L of the analyzed sample were added to the samples. The samples were shaken and stored under laboratory conditions for 12 hours. The concentration of PAHs before and after the oxidation process were determined.}, abstract={The quantitative and qualitative chromatographic analysis was carried out using a gas chromatograph coupled with a mass spectrometer (GC-MS). The total concentration of 8 PAHs before oxidation reached the value of 9150 ng/L The concentration of 4-ring compounds and 5-ring PAHs were equal to 6390 ng/L and 2760 ng/L, respectively. The highest decrease (93%) the sum of 8 hydrocarbons using a dose of oxidizer 7.4 ml/L and in the presence of titanium catalyst was achieved.}, type={artykuł}, title={Catalytic oxidation of PAHs in wastewater = Katalityczne utlenianie WWA w ściekach}, keywords={utlenianie, H2O2, GC-MS, ścieki koksownicze, katalizator platynowy, katalizator tytanowy, WWA, oxidation, coking wastewater, platinum catalyst, cobalt catalyst, titanium catalyst, PAHs}, }
