Contamination of soil and water by crude oil and other related products becomes a worldwide problem. Petroleum hydrocarbons come into the environment through accidents, spills or leaks, from industrial releases, or as byproducts from commercial or domestic uses. The removal of hydrocarbons from contaminated soil or water is an essential practice because of environmental concern, and in order to avoid surface and groundwater contamination. Hydrocarbon components in petroleum are composed of paraffinic (linear or branched), naphthenic and aromatic groups. Different methods can be used to remove the hydrocarbons from environment, but usually they are not fully satisfying. This report deals with the degradation of water soluble fraction (WSF) of crude oil using both sonolysis and photocatalysis. WSF of crude oil were analyzed before and after degradation using gas chromatography mass spectrometry (GC/MS), liquid state nuclear magnetic resonance (1H NMR), Fourier transform ion cyclotron mass spectrometry (FT-ICR) and fluorescence spectrometry, but in this report only the GC/MS analysis will be presented

Abstract
Contamination of soil and water by crude oil and other related products becomes a worldwide problem. Petroleum hydrocarbons come into the environment through accidents, spills or leaks, from industrial releases, or as byproducts from commercial or domestic uses. The removal of hydrocarbons from contaminated soil or water is an essential practice because of environmental concern, and in order to avoid surface and groundwater contamination. Hydrocarbon components in petroleum are composed of paraffinic (linear or branched), naphthenic and aromatic groups. Different methods can be used to remove the hydrocarbons from environment, but usually they are not fully satisfying. This report deals with the degradation of water soluble fraction (WSF) of crude oil using both sonolysis and photocatalysis. WSF of crude oil were analyzed before and after degradation using gas chromatography mass spectrometry (GC/MS), liquid state nuclear magnetic resonance (1H NMR), Fourier transform ion cyclotron mass spectrometry (FT-ICR) and fluorescence spectrometry, but in this report only the GC/MS analysis will be presentedI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
