Abstract
The NaBiO3 samples (NaBiO3 · nH2O) used in photooxidation of polycyclic aromatic hydrocarbon were obtained through heating NaBiO3 · 2H2O. The samples were characterized by X-ray diffractometer and ultraviolet-visible spectrophotometer. The photooxidation of anthracene and Benz[a]anthracene over NaBiO3 · nH2O was investigated, respectively. The intermediates were analysed by gas chromatography-mass spectrometer. The results indicated that the prepared NaBiO3 samples showed considerable photooxidation activity and stability for PAHs degradation under visible light irradiation. The possible reaction pathways of the decomposition of the two polycyclic aromatic hydrocarbons were proposed.
