Detection of pesticide residue parameters in exported grains/food

Method for the determination of multiple organic phosphorus pesticide residues in exported grains - Gas chromatography-mass spectrometry method - Scope 1- This standard specifies the determination of dichlorvos, acephate, propafenophos, dithion, terbufos, methyl ethyl mixed phosphorus, diazinon, ethimidophos, methyl midophos, malathion, fenvalerate, parathion, bethion, rice powder Gas chromatography-mass spectrometry method for detecting and confirming the residues of 16 organic phosphorus pesticides, including butylaminophos and benthion (see Table A.1 in Appendix A). This standard is applicable to the gas chromatography-mass spectrometry method for the detection and confirmation of 16 types of organic phosphorus pesticide residues, including dichlorvos, acephate, propanophos, dicarbothion, terbufos, methyl ethyl mixed phosphorus, diazinon, ethylthion, methyl midophos, malathion, phoxim, parathion, bethion, Daofengsan, butamidophos, and benthion, in corn, brown rice, wheat, and buckwheat. The following normative references are essential for the application of this document. For dated references, only the dated version applies to this document. For undated references, the latest version (including all modification orders) applies to this document. GB/T 6682 Specification of Water for Analytical Laboratory and Test Methods 3. 16 kinds of organophosphorus pesticides, such as dichlorvos, acephate, propafenphos, fenthion, terbufos, methyl acetophos, diazinon, ethambuphos, methyl midophos, malathion, mofethion, parathion, fenthion, Daofengsan, butymidophos, benthion and so on, remaining in the principle samples were extracted homogeneously with water acetone, distributed liquid-liquid with dichloromethane, and purified with gel chromatographic column, After passing through a solid phase extraction column of graphitized carbon black and Florisilica, purification was carried out, and the eluent was concentrated and dissolved to volume. Gas chromatography mass spectrometry was used for detection, and external standard method was used for quantification
