Using phenanthrene as a model analyte, we show that extraction from aqueous solution is possible via adsorption onto the surface of a poly(tetrafluoroethylene)-coated magnetic stir bar. Desorption from the stir-bar via ultrasonic agitation in acetoni

The deacidification of high-acidity oils from Black cumin seeds (Nigella sativa) was investigated with supercritical carbon dioxide at two temperatures (40 and 60°C), pressures (15 and 20 MPa) and polarities (pure CO2 and CO2/10% MeOH). For pure CO2
