Abstract

Abstract:

A method using solid phrase extraction (SPE) followed by gas chromatography with flame photometric detection (GC-FPD, S-type filter) has been developed for determining ametryn residue in 4 plant-derived foods. Samples were extracted and cleaned up on an ENVI-Carb/NH2 column using acetonitrile/toluene (7:2) as elution solvent. The quantification method employed was external standard method. Under the selected analytical conditions, the detection limit was 0.01 mg/kg. Average recovery rates for the analyte in rice, apple, banana and eggplant spiked at 3 levels ranged from 88.0% to 100.0% with relative standard deviations (RSD) from 3.71% to 11.71%. This method is sensitive, precise and reproducible and has stable recovery. These figures of merit demonstrate its good applicability.

Key words: ametryn, plant-derived food, residue, GC-FPD, S-type filter
