Determination of Organophosphrous Pesticides in Frozen Dumplings with Accelerated Solvent Extraction and Chromatography |
| |
| Abstract: | A accelerated solvent extraction( ASE) and online purification method to determine the organophosphrous pesticide residues in frozen dumplings was established. With high speed,stability,reliability and easy operation,this method obtained good linearity for determining 15 pesticides with concentration between 0. 05- 0. 5μg/mL( the correlation coefficients( r) were all greater than 0.998 5). The detection limits ranged from 0. 006mg /kg to 0. 05mg /kg. The average recoveries of organophosphrous pesticides were between 84. 88% and 107. 1%.The relative standard deviations for 15 organophosphrous pesticides were between 1. 92% and 1. 40%. |
