摘要: A method was developed for the determination of chlorpyrifos residues in paddy field aquatic products by ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). Samples were extracted with acetonitrile and purified by using 0.2 g primary secondary amine (PSA) sorbent and 1.2 g MgSO4. The target compound was separated on a Hypersil GOLD C-18 column (100 mm x 2.1 mm, 5 mu m), and was determined using a heated electrospray ionization (HESI) source in the positive ion selective reaction monitoring (SRM) mode. The analyte was quantified with external standard using the matrix. matched standard cal. ibration curve method. The results showed that good linearities were obtained in the range of 0.5-100.0 mu g/L, and the correlation coefficients were greater than 0.999. The spiked recover. ies of chlorpyrifos ranged from 86.2% to 103.6% with RSDs of 3.5%-7.6% (n = 6). The limits of detection and quantification were 0.25 mu g/kg and 0.5 mu g/kg, respectively. This method is simple, quick, sensitive, and suitable for the rapid determination and analysis of chlorpyrifos residues in paddy field aquatic products.
