Abstract
The use of monoethylene glycol as an
extraction medium for removing phenol and alkyl phenols in
organic matrixes such as hydrocarbons is introduced and
combined with a practical analytical multidimensional gas
chromatography approach. The analytical approach has been
successfully developed for the characterization of phenol,
cresols, xylenols, and alkyl phenols like 4-ethylphenol and
2,3,5-trimethylphenol. The technique employs a single-step
extraction of the analytes with monoethylene glycol and
sonication, followed by multidimensional gas chromatography
with mass spectrometry in selected ion monitoring mode for the detection and quantitation. Extraction efficiency of phenol
approached 100% while cresols, xylenols, and 4-ethylphenol were 97% or higher and 2,3,5-trimethylphenol was better than 91%
under the analytical conditions used. With the technique described, a complete analysis can be conducted in less than 16 min.
Reproducibility of area counts at two levels, namely, 5 ppmw and 50 ppmw over a period of 2 days were found to be less than 4%
(n = 20). The analytes of interest was found to be linear over a range from 100 ppbw to 250 ppmw with correlation coefficient of
at least 0.999 and detection limit of 50 ppbw. Spike recoveries from 500 ppbw to 250 ppmw for all analytes range from 96 to 102%.
