Determination of Diflubenzuron Residues in Vegetables by UPLC-MS/MS

Abstract:

The conditions for detecting residues of diflubenzuron in vegetables by ultra high performance liquid chromatography tandem mass spectrometry were studied. The target was extracted with acetonitrile for 2 min with a homogenizer. The extaction was purifide by a conditioned Florisil SPE cartridge, and then was detected by ultra high-performance liquid chromatography with tandem mass spectrometry. The average recovery was in the range from 87.8 %- 99.2 % at spike levels of 0.1, 1.0 and 10 mg/kg in vegetables, and relative standard deviations was in the range of 4.2 %-8.9 %. The proposed method is fast, simple, sensitive and accurate.
