Abstract: An analytical method for the determination of nitenpyram residue in cabbage and soil using gas chromatography was established. The nitenpyram residue was extracted from cabbage and soil with acetone-water (4:1, v/v), cleaned up by a Florisil column, and then detected by gas chromatography-electron capture detection (GC-ECD). At the spiked level range from 0.02 to 2.00 mg/kg, the average recoveries of nitenpyram were 88.73%~94.13% and 90.82%~96.27% with the relative standard deviations (RSDs) of 3.09%~7.39% and 2.01%~4.92%in cabbage and soil, respectively. The limit of detection of nitenpyram was 0.02 mg/kg. The method is fast, sensitive, simple, reproducible and practical for the determination of nitenpyram residue in environmental systems.
