Study on the Determination Method of the Residual Quantity of Multi-Organophosphorus Pesticides in Honey

SUI Wu-Bin(Department of Chemistry,Zaozhuang College,Zaozhuang,Shandong 277101)  
[Objective] The purpose was to seek for the optimum method to detect the residual quantities of multi-organophosphorous pesticides in honey.[Method] With DB-35 silica capillary column for split stream sampling and programmed heating,flame photometric detector(FPD) with optical filter with phosphorous for detecting,and high purity nitrogen,air and hydrogen as carrier gas,the method of detecting the residual quantities of 8 organophosphorous pesticides(DDVP,methamidophos,phorate,dimethoate,methyl parathion,malathion,chlorpyrifos and parathion) in honey by gas chromatography method was established.[Result] 8 kinds of organophosphorous pesticides had good linear relationship(r0.995 5) in the content range of 1~100 ng/mL,their least detective ranges were 0.021~0.1 μg/mL and the additive recoveries were in 81 %~100 %.[Conclusion] The accuracy,sensitivity,recovery and reproducibility of the method all accorded with the requirement of detective technique of pesticide multi-residue.
