| Notes | Objective To study the effects of different drying processes on 6 kinds of organophosphate pesticide residues including oxygen dimethoate, dichlorvos, methyl parathion, phorate, phosphorus absorption and parathion in Chrysanthemum morifolium. Methods Chrysanthemum polluted by organophosphate pesticides were processed by air-drying after steaming 3 min, 50 ℃ heat-drying, air-drying and drying, respectively, then extracted with acetonitrile, purified by Carb/PSA solid phase extraction, and detected by gas chromatography（GC, equipped with FPD detector）. Results Six kinds of organophosphate pesticides had good linear relationships in the range of 0.01~0.08 μg/m L with the correlation coefficients r0.997, the recoveries were in the range of 78.5%~94.3%, RSDs were in the range of 1.7%~5.9%, and the limits of quantitation were ranged from 0.53 to 1.16 μg/kg. Six kinds of organophosphate pesticides had not been detected in the 3 kinds of dried chrysanthemums. Conclusions Three kinds of drying methods can significantl |
