摘要: 采用改进的QuEChERS方法，结合超高效液相色谱-串联质谱法（UPLC-MS/MS），建立了热带水果中杀虫双残留的测定方法。热带水果经含1%（v/v）乙酸的乙腈溶液二次提取，200 mg N-丙基乙二胺（PSA）、100 mg C18、300 mg MgSO₄和500 mg柠檬酸氢二钠净化。采用CAPCELL CORE PC亲水色谱柱进行分离，在负离子多反应监测（MRM）模式下检测，外标法定量。结果表明，杀虫双在0.1~10.0 μg/L范围内线性关系良好，相关系数（r²）为0.9993，检出限和定量限分别为0.015 μg/kg和0.05 μg/kg，加标回收率为81.0%~88.3%，相对标准偏差（RSD）为3.9%~6.2%。该法净化效果好，灵敏度高，适于热带水果中杀虫双残留的快速定性和定量分析。

Abstract: A method for the determination of bisultap in tropical fruits was developed by modified QuEChERS method and ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). The tropical fruit samples were twice extracted with acetonitrile containing 1% (v/v) acetic acid, and purified by 200 mg of primary secondary amine (PSA), 100 mg of C18, 300 mg of MgSO₄ and 500 mg of disodium hydrogen citrate. The analyte was separated on a CAPCELL CORE PC hydrophilic column, detected in the negative ion multiple reaction monitoring (MRM) mode, and quantified by external standard method. A good linear relationship in the range of 0.1-10.0 μg/L was obtained with the correlation coefficient (r²) of 0.9993. The limit of detection and limit of quantification were 0.015 μg/kg and 0.05 μg/kg, respectively. The spiked recoveries were in the range of 81.0%-88.3% with the relative standard deviations from 3.9% to 6.2%. The method has good purification effect and high sensitivity, and is suitable for the rapid analysis of the bisultap residues in tropical fruits.
