The use of
microemulsions for the extraction and simultaneous pre-concentration of
maltenes as potential chemical markers to identificate hydrocarbon deposits
Abstract
Microemulsions
as extractants in the analysis of oil chemical markers with following
decomposition of microemulsions were used for GC-MS determination of oil
components. Due to of its hydrophobicity, oil components migrate into the
organic phase after the decomposition of microemulsions and pre-concentrate due
to the volume reduction of organic phase. It is shown that as the concentration
of the precipitant increases, the coefficient of pre-concentration of chemical
markers increases (up to 8-10 times). The proposed technique itself is
characterized by low detection limits, good selectivity and reproducibility.
Key words:
microemulsion, sodium dodecyl sulphate, gas chromatography, oil chemical
markers, pre-concentration.
