Abstract

A method for the analysis of 8 organophosphorus (OP) with wide range of physico-chemical properties in Chrysanthemum flower was developed and validated. The procedure involved the extraction of the spiked sample (5 g) with 100 mL acetone and the final volume was not subjected to any clean-up procedure. The analyte concentrations were determined through gas chromatography GC-9A, equipped with flame photometric detector (FPD). The mean recoveries of the spiked blank samples at three concentrations for different pesticides were found in the range of 91.00–99.67 % and relative standard deviation lower than 12.0%. Limit of detection (LOD) of the method ranged between 0.06 and 0.08 mg kg-1 and the limit of quantitation (LOQ) were varied from 0.09 to 0.1 mg kg-1. The selected parameters for method validation (precision, accuracy, calibration function, sensitivity, selectivity, limit of detection and limit of quantitation) were within the acceptable limits according to the EU criteria (SANCO) for the 8 insecticides included in the validation.
