Popis: The aim of this work was to study the application of photo-Fenton process to remediate oil contaminated soil. In this work, the influence of irradiation time, hydrogen peroxide concentration and the use of visible, UV-A and UV-C light were investigated. In addition, the presence of external catalyst (Fe2+) was assessed. The photocatalytic treatment of petroleum contaminated soil was an efficient method for removing the total organic content, achieving about 50% of TOC removal at the end of the reaction time. The use of UV-A light promoted higher TOC removal than other irradiation sources, increasing 17 and 10% the TOC removal when compared to UV-C and visible light, respectively. In the case of treatment using UV lamps, the addition of external Fe was not necessary to achieve high levels of TOC removal.
