    Author: Tiburtius ER, Peralta-Zamora P, Emmel A.
    Journal: J Hazard Mater; 2005 Nov 11; 126(1-3):86-90. PubMed ID: 16051429.
    Abstract:
    In this study, the efficiency of advanced oxidative processes (AOPs) was investigated toward the degradation of aqueous solutions containing benzene, toluene and xylenes (BTX) and gasoline-contaminated waters. The results indicated that BTX can be effectively oxidized by near UV-assisted photo-Fenton process. The treatment permits almost total degradation of BTX and removal of more than 80% of the phenolic intermediates at reaction times of about 30 min. Preliminary investigations using water contaminated by gasoline suggest a good potentiality of the process for the treatment of large volumes of aqueous samples containing these polluting species. Heterogeneous photocatalysis and H2O2/UV system show lower degradation efficiency, probably due to the heterogeneous character of the TiO2-mediated system and lost of photonic efficiency of the H2O2/UV system in the presence of highly colored intermediated.
