Photocatalytic degradation of polycyclic aromatic hydrocarbons on soil surfaces using TiO2 under UV light

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.

The photocatalytic degradation of phenanthrene (PHE), pyrene (PYRE) and benzo[a]pyrene (BaP) on soil surfaces in the presence of Fe2O3 using ultraviolet (UV) light source was investigated. The effects of various factors, namely Fe2O3, soil pH, and humic acid, on the degradation performance of polycyclic aromatic hydrocarbons (PAHs) were studied. The results show that photocatalytic degradation of PAHs follows the pseudo-first-order kinetics. Catalyst Fe2O3 accelerated the photodegradation of PHE, PYRE and BaP significantly. In acidic or alkaline conditions, the photocatalytic degradation rates of the PAHs were greater than those in neutral conditions. Humic acid significantly enhanced the PAH photocatalytic degradation by sensitizing radicals capable of oxidizing PAHs.

Effect Of Light

Polycyclic aromatic hydrocarbons (PAHs) are a class of genotoxic environmentalcontaminants and are always exposed to solar radiations. Fluorenes are important PAHswidely distributed in nature and hence the studies in the effect of light on them are of ulmostsignificance. Therefore in this paper, we have studied the photo irradiations of fluorene (1)and 9-fluorenone (2) with UV light in different solvents, which results in the formation ofdifferent products.
