- Abstract:
- A method of solid phase extraction/liquid chromatography-electrospray ionization tandem mass spectrometry (SPE/LC-ESI-MS/MS) for determination of thiabendazole in surface water was explored. The samples were extracted by SPE column. Liquid chromatography separation was performed on an Agilent ZORBAX SB-C18 column with a gradient elution of 0.2% formic acid acetonitrile and 0.2% formic acid as the mobile phases. Electrospray ionization and qualitative and quantitative analysis were carried out under the positive ion multi-reaction monitoring mode. Good linearity was observed in the range of 0-100 μg/L thiabendazole with correlation coefficient 0.999 2, and the limit of detection (LOD) was 0.16 ng/L. At three different standard addition levels (5.0， 20.0 and 100 ng), average recovery rates of thiabendazole in practical samples ranged from 74.7% to 86.5% with RSD between 6.1% and 12.9%. The method was applied to detect thiabendazole concentration in 68 samples of surface water in Hangzhou, and thiabendazole in 25 samples was detected.
