摘要: In the present study, a simple and efficient preconcentration method was developed using ultrasound-assisted extraction followed by solid-phase extraction followed by dispersive liquid-liquid microextraction for the extraction and determination of trace amount of chloramphenicol in chicken meat. The sample was extracted with acetonitrile and EDTA-McIlvaine buffer under ultrasonication, followed by solid-phase extraction and dispersive liquid-liquid microextraction. In order to obtain high extraction efficiency, the parameters …
