Analysis of Permethrin in Cole by Dispersive Solid Phase Extraction
A new dispersive solid phase extraction (DSPE) method coupled with GC detection was established for determination of permethrin residue in cole.The proposed DSPE method was carried out using acetonitrile as the extraction solvent,and neutral alumina oxide as dispersive adsorbent.The factors that affected DSPE efficiency were validated in terms of extraction solvent,extraction time,and dispersive adsorbent kinds and interaction time.The developed method could give satisfactory recovery (91.2-107.4%) with RSD≤4.9%.Good linearity was observed in the range of 0.005-1.19 mg/g with the correlation coefficients (r2) of 0.9992.The detection limits for permethrin was of 0.43 μg/g.The method had been successfully applied to the analysis of permethrin esidues in cole samples.
