The present invention relates to a kind of while determining 12 kinds of methods of OPEs residuals in water sample and deposit.The invention belongs to the determination techniques field of organophosphorus ester, a kind of 12 kinds of methods of phosphate compounds residual in utilization high performance liquid chromatography mass spectrometric hyphenated technique combination SPE, liquid-liquid extraction detection water body and deposit are disclosed.Water sample is enriched with through HLB solid-phase extraction columns, and deposit is extracted through ultrasonic solvent, is monitored ion mode with high performance liquid chromatography GC-MS MRM and is analyzed, quantified by external standard method.The method of the present invention is for most of OPEs, and detection limit is low, and good stability, detection sensitivity is high, for the rapid screening of OPEs in water body and deposit, 12 kinds of detection requirements of OPEs residuals in water body and deposit is disclosure satisfy that substantially. |
