SFE Used to Recover Aflatoxin from Soil

Researchers from US EPA National Exposure Research Laboratory (Research Triangle Park, North Carolina) and East Carolina University (Greenville, North Carolina) used supercritical fluid extraction (SFE) to recover aflatoxin B1 from fortified soil.

Researchers from US EPA National Exposure Research Laboratory (Research Triangle Park, North Carolina) and East Carolina University (Greenville, North Carolina) used supercritical fluid extraction (SFE) to recover aflatoxin B1 from fortified soil. They examined the effects of temperature, pressure, modifier and modifier percentage, and extraction type on the analysis. They found that desorption from the soil was the limiting factor in analyte recovery and that the static phase was more important than the dynamic phase.
