| Description |
The single drop microextraction method was developed for the determination of ten
organochlorine pesticides in tea brews using gas chromatograph-electron capture detector.
The optimized parameters for effective extraction required a 2 μL drop of n-hexane at the
tip of a microsyringe immersed in 5 mL of a diluted tea brew sample for 25 min and stirred
at 600 rpm. The limit of detection in the range of 0.01 to 0.025 μg/L, with relative standard
deviation of repeatability and reproducibility, was in the range of 1–10 and 8–24%. The relationship
of the measured signal was a linear function (>0.9863) of concentration and the
recovery method ranged from 92–116%. The single drop microextraction method showed the
advantage of being easy to operate, low consumption of organic solvent, and high extraction
efficiency.
