Article Preview

The photocatalytic degradation of pyrene (PYRE) and benzo[a]pyrene (BaP) on soil surfaces in the presence of Fe2O3 using ultraviolet (UV) light source was investigated in a photo chamber, in which the temperature was maintained 30 . The effects of UV irradiation intensity and UV wavelength on the degradation performance of polycyclic aromatic hydrocarbons (PAHs) were studied. The results show that with the intensity of UV irradiation being enhanced, the photocatalytic degradation rates of PAHs were increased. Photocatalytic degradation rates of PYRE and BaP on soil surfaces with 5% Fe2O3 were different at UV irradiation wavelengths of 254, 310 and 365 nm, respectively.
