Abstract

A gas chromatography - mass spectrometry (GC-MS) analysis method for detecting five kinds of high-toxic pesticides in Chinese tea was established. Gel permeation chromatography (GPC) was used as a sample preparation method. Purified samples were analyzed by GC-MS, detected in selected ion monitoring mode, and quantitated using the external standard method. The results showed a good linearity within the range from 0.005 mg/L to 0.500 mg/L. The average recovery rates of three spiked levels were 93.86% to 106.31%. All relative standard deviations (RSDs) were less than 10%. The detection limit was 0.0005 to 0.0020 mg/kg. This method is stable and reliable, simple to operate, and suitable for detection and analysis of trace organophosphorus pesticides in Chinese tea.
