Determination of Organophosphorus Pesticide Residues in Flos Chrysanthemi by Matrix Solid Phase Dispersion-Gas Chromatography
摘要
Abstract
An analytical method was developed for the simultaneous determination of 14 organophosphorus pesticides in Flos Chrysanthemi by using matrix solid phase dispersion (MSPD) and gas chromatography (GC). Flos Chrysanthemi samples were extracted with acetonitrile-acetone (4:1, V/V) and cleaned up by mallix solid phase dispersion (MSPD), eluted with acetonitrUe toluene (3:1, V/V) and determined by GC with a flame photometric detector. The recovery rates of 14 organophosphorus pesticides were 84.54%~ 108.54% with relative standard deviation of 0.66% - 6.31% at spiked levels of 0.05 - 1.0 mg/kg. The limit of detection was 0.01 -- 0.04 mg/kg. The proposed method was characterized by simplicity, higher sensitivity and accuracy. The contents of dimethoate, chlorpyrifos and phosfolan in Huangshan Gongju chrysanthemum were 1.68, 0.17 mg/kg and 0.28 mg/kg, respectively, the content of chlorpyrifos in Hangbaiju chrysanthemum was 0.09 mg/kg, and the contents of dimethoate, chlorpyrifos and phosalone in Hangbalju chrysanthemum bud were 0.25, 0.14 mg/kg and 0.08 mg/kg, respectively as determined by this method.关键词
