Abstract
A supercritical fluid extraction (SFE) method is proposed for the reco very of three sulfonamides from chicken liver. Samples were extracted at 680 bar and 40 degrees C using unmodified carbon dioxide and were c ollected free of co-extracted artifactual material on an in-line neutr al alumina sorbent bed. High recoveries of sulfamethazine (SMZ), sulfa dimethoxine (SDM) and sulfaquinoxaline (SQX) were obtained from chicke n liver samples fortified at levels from 1000 to 50 ppm.
