| Abstract: | Objective]The aim of this experiment was to establish a swift, efficient and precise analytical method for simultaneously determining ten organophosphorus pesticides multi-residues in chewing cane. Method ]Samples were extracted with acetonitrile, pre-treated with modified QuEChERS technology and then determined by GC with NPD. Result]The linear relations among ten organophosphorus pesticides were obtained in the concentration range fi＇om 0.1 to 10.0 mg/kg with the correlation coefficients range from 0.9968 to 0.9998. Under 0.02-2.0 mg/kg added concentration, recovery rates of ten organophosphorus pesticides were ranged from 75.69% to 108.31%, the relative standard deviation found was from 2.94% to 9.23% and the lowest detection limit was 0.010-0.035 mg/kg. Conclusion]The established QuEChERS-gas chromatography method, which is sensitive, accurate, convenient and reliable and had high recovery rate and great separation effects, could meet the demand of analyzing pesticides residues. |
