文摘

Ionic liquid in situ DLLME was developed for the extraction of PCBs and acrylamide. Headspace GC was used for detecting analytes from the IL-based extraction solvent. The method showed good matrix-compatibility with complex milk and coffee samples. The optimized method exhibited high sensitivity and fast sampling time.
