摘要：Twenty nine kinds of organophosphorus pesticides were simultaneously measured by FPD-GC with two kinds of capillary columns (DB-210 and CBP-10). Reproducibility for peaks area of the pesticides in chromatograms were the range of 4.6-21.6%. Determination method of the 29 pesticides in foods was systematically established as follows. A) Pesticides in vegetables and fruits were extracted with acetone, re-extracted with 20% CH₂Cl₂-hexane and determined by GC. Recoveries of the pesticides in cucumber, potato, Japanese persimmon, cabbage, apple and mandarin orange were the range of 53.2-102.2%. B) Pesticides in garlic, onion, scallion were extracted, re-extracted by the same method with A, then purified by silica-gel column chromatography. Recoveries of the pesticides were the range of 31.2-89.9%. C) Pesticides in rice, wheat, soy bean and corn were extracted, re-extracted by the same method with A, then partitioned with hexane-acetonitrile and purified by silica-gel column chromatography. Recoveries of the pesticides were the range of 36.7-95.8%.
