In this study,copper(Ⅱ) isonicotinate was first used as online cleanup adsorbent in selective pressurized liquid extraction(SPLE) for determination of trace residues of polychlorinated biphenyls(PCBs) in fatty food samples.The adsorbent to sample ratio,extraction temperature,extraction time,and recycle times,etc.were optimized.
