摘要
A multiresidue method using gas chromatography with electron-capture detection (ECD), nitrogen-phosphorus detection (NPD), or flame ionization detection (FID) has been developed for the determination of triazole residues such as triadimefon, penconazole, hexaconazole, diniconazole, and organophosphorus residues such as chlorpyrifos-methyl. The method has been successfully applied to the analysis of tomatoes and eggplant samples. The recoveries obtained from NPD detector for tomatoes and eggplants were in the range 62.0-109% and 66.0-104% with the relative standard deviation varied from 5.0 to 13.1% and 3.2 to 18.0%, respectively. The method was validated and applied for the determination of triazole and organophosphorus pesticides in agrochemical formulations within the recoveries of 96.3-107.2%.
