Abstract
|
Describes
a liquid-phase microextraction (LPME) method for the determination of sulfur
compounds in Arabian crude oil and diesel. Researchers employed a range of
sulfur compounds, including benzothiophene, dibenzothiophene and their
derivatives, for model compounds.
They conducted analyses by gas chromatography equipped with a sulfur chemiluminescence detector (GC-SCD). Under optimum conditions, they obtained a linearity for the extraction of sulfur compounds between 0.10 and 250 μg mL−1 with the correlation of determination ranging from 0.98 to 0.99. Applying the same optimum conditions, the extraction of 77–91% of the sulfur compounds in the Arabian light, Arabian medium and Arabian heavy, and diesel was achieved. |
