The photocatalytic oxidation of pyrene preadsorbed on TiO 2 is examined in aqueous suspension under UV irradiation. Chemical oxygen demand measurements, UV-VIS spectrophotometer, infrared spectrometer and GC-MS analytical techniques were used to monitor the formed intermediates. During the oxidation processes, the ring-open reaction, hydroxylation and ketolysis occurred to produce some intermediate...
The photocatalytic oxidation of phenanthrene was investigated in aqueous TiO 2 suspensions under UV light irradiation. Chemical oxygen demand (COD) measurements, UV-Vis spectrophotometer, IR spectrometer and gas chromatography-mass spectrometry (GC-MS) analytical techniques were used to monitor the reaction process. Some factors affecting the photodegradation rate were studied and some aromatic...
