Abstract:
OBJECTIVETo establish an analysical method for the quantitative determination of 18 kinds of organophosphate pesticide residues in Flos Lonicerae.
METHODThe pesticides in samples were extracted with acetone by Ultrasonic wave Assistant Extraction (UAE), purified by Solid-Phase Extraction (SPE). Using PFPD detecter gas chromatography with HP-1701 column.
RESULT AND CONCLUSIONAll 18 pesticides were separated well in 30 minutes. The detection limits was 4.0-18.0 microg x kg(-1). The range of recovery and RSD were 83.64%-88.65% and 2.8%-6.0%, respectively. And it met the requirements of pesticide multi-residues analysis.
