Heavy fuel oils, used as heating oils in thermal power plants, are known to contain a wide range of organic compounds; among these, the volatile monocyclic aromatic hydrocarbons receive particular attention, since they are potentially carcinogenic. Here, a methodology for the determination of these hazardous compounds in a complex matrix, such as heavy fuel oil, is described. Such a methodology makes use of headspace solid-phase micro-extraction as a pre-analytical technique, followed by gas chromatographic-mass spectrometric analysis. For quantitative purposes, internal standard solutions were prepared using deuterated BTEX solubilized in white mineral oil. Actual samples analyses are also reported.

Abstract
Heavy fuel oils, used as heating oils in thermal power plants, are known to contain a wide range of organic compounds; among these, the volatile monocyclic aromatic hydrocarbons receive particular attention, since they are potentially carcinogenic. Here, a methodology for the determination of these hazardous compounds in a complex matrix, such as heavy fuel oil, is described. Such a methodology makes use of headspace solid-phase micro-extraction as a pre-analytical technique, followed by gas chromatographic-mass spectrometric analysis. For quantitative purposes, internal standard solutions were prepared using deuterated BTEX solubilized in white mineral oil. Actual samples analyses are also reported.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
