Jm. Levy et al., USE OF MODIFIERS IN ONLINE AND OFF-LINE SUPERCRITICAL-FLUID EXTRACTION, HRC. Journal of high resolution chromatography, 16(6), 1993, pp. 368-371
For many applications using supercritical fluid extraction (SFE), modi
fiers may be required. This paper will present some findings regarding
the use of various modifiers including methanol, hexane, acetone, chl
oroform, dichloromethane, toluene, and tributylphosphate, in on-line a
nd off-line SFE with cryogenic adsorbent trapping. The specific applic
ations involved the extractions of petroleum hydrocarbons and pesticid
es from naturally incurred soils.
