Abstract:

A dual-column gas chromatographic method was developed for the multi-residue determination of organophosphorus pesticides in fruit juice. Samples were extracted with acetone, and the resulting extract was cleaned up on Carb/NH2 SPE cartridge. The chromatographic separation was achieved on DB-1701 and DB-35ms capillary columns. Analytes were detected with FPD. The average recoveries of 6 replicates for analytes in blank samples spiked at 3 levels ranged between 75.23% and 98.53%, with relative standard deviations between 0.97% and 8.16%. The limits of detection were within the range of 10-60 μg/kg.

Key words: fruit juice, organophosphorus pesticides, multi-residues, dual column gas chromatography, FPD
