The use of microemulsions for the
extraction of phtalic acid esters from soils with subsequent decomposition
of microemulsions, simultaneous

Abstract
The use of microemulsions for the
extraction of phtalic acid esters from soils with subsequent decomposition of
microemulsions, simultaneous pre-concentration of dialkhylphthalates in organic
phase and following GC-MS determination of target compounds was shown. The
coefficient of concentration was 18. Method is characterized by low detection
limits, good selectivity and reproducibility.
Key words: microemulsion,
dialkylphthalates, gas chromatography, mass spectrometry, pre-concentration.
