Double-Column Capillary GC Determination of the Organophoshate Pesticide Residues in Tea

摘要：

In this research, a determination of 6 organophosphorus pesticide residues in the tea has been established by capillary gas chromatography. After rotary steam and condensation, the sample is filtered through 0.2μm membrane and determined by gas chromatography FPD detector. The peak time of six pesticide ranges from 9.077min to 32.420min. The average recovery ranges between 90.5％ and 110.6％, RSD, between 13％ and 8.1％, detection limits, between 0.0066μg·kg-1 and 0.0085μg·kg-1, and the correlation coefficient of the standard curve, between 0.99848 and 0.99988 in the concentration range of O.O1-1.Omg·L-1.
