We report a multi-residue pretreatment technique, termed temperature-assisted ionic liquid dispersive liquid-liquid microextraction, and demonstrate its application to simultaneous extraction of polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs). An ionic liquid was used as the extraction solvent and dispersed into the liquid sample (water, urine) with the help of methanol...
In this article, dispersive liquid–liquid microextraction (DLLME) and gas chromatography–electron capture detection (GC–ECD) were presented for the extraction and determination of five polychlorinated biphenyls (PCBs) in soil samples. Acetone was used as extraction solvent for the extraction of PCBs from soil samples. In DLLME, the target analytes in the extraction solvent were rapidly transferred...
