文摘

In this paper, a simple and efficient directly suspended droplet microextraction (DSDME) method has been developed and optimized, which can be applied on extracting organochlorine pesticides (OCPs) in beverage for gas chromatography–electron capture detector (GC-ECD) analysis. The optimal DSDME was adding 100?μL of isooctane into 5?mL of the beverage sample and stirred for 10?min at 1,000?rpm. The relative recoveries of the DSDME method were ranged from 81 to 117?% (relative standard deviations were 2-0?%, n--). The limits of detections were 0.8-.0?ng/L. Furthermore, DSDME was applied to rapidly determine the OCPs in tea beverage and the results suggested that the method can be used as rapid determination of OCPs in the tea beverage.
