dc.description.abstract | Thermal extraction-GC-MS (TE-GC-MS) is a relatively new analytical technique which demonstrates a large potential for the analysis of various solid matrices. This technique provides a rapid quantitative and simultaneous determination of a wide range of volatile and semi-volatile organic compounds without laborious sample preparation or any chemical pre-treatment. Its amenability to automation and coupling with on-line detection methods makes TE-GC-MS a promising technique, not only in laboratory analysis, but also for in situ emission monitoring. However, the number of studies dedicated to the application of TE-GC-MS to fly ashes, which are an unavoidable by-product of any thermal industrial process and also the sink of many environmental pollutants, is limited. The ability of TE-GC-MS to analyse a wide range of trace semi-volatile dioxin surrogate compounds in fly ash samples is investigated as an alternative to the well-established solvent extraction-GC-MS analysis (SE-GC-MS). Reproducibility, the effect of TE temperature, time, flow, and the influence of the analysed matrix are studied. Dedicated experiments demonstrate that the conversion (dechlorination and in situ formation) of target analytes and the decomposition of the fly ash matrix can take place at elevated TE temperatures and during prolonged TE times. Moreover, these effects are matrix-specific and vary from sample to sample. After optimizing the TE parameters, two fly ash samples of different origins are analysed and more than 50 individual analytes representing different classes of aromatic compounds are quantified and compared with those available from the SE-GC-MS analysis.
