摘要：

When separating volatile compounds from aqueous solution using supercritical carbon dioxide (SC CO2), methods to bring SC CO2 into contact with volatile compounds in the solution are very important. An extraction using micro bubble, gaseous, supercritical, and liquid CO2 generated by a filter nozzle was carried out. Under optimal conditions (20 MPa, 35 degrees C), > 95% of volatile compounds consisting of 6 to 12 carbon atoms could be removed by extraction for 40 min at CO2 flow rate, 4.0 g/min. Extraction al 35 degrees C could achieve either a selective or nonselective separation by adjusting the extraction pressure, since the effect of pressure on extraction ratio was most significant at 35 degrees C.
