Abstract: The method for the determination of 15 organophosphorus residues in rice was established by gas chromatography. The method was verified by flame photometric detector FPD+, external standard method and automatic injection under established gas chromatography. The results showed that the 15 organophosphorus pesticide were well separated on DB1701 quartz capillary column by temperature programmed. The method had high recovery, good reproducibility and short analysis time. It was an accurate, stable and simple method, which can fully meet the needs of practical application.

Key words: external standard method, rice, gramineous enemy, flame photometric detector FPD+
