Ionic liquid-based dispersive liquid–liquid microextraction followed high-performance liquid chromatography for the determination of organophosphorus pesticides in water sample
TL;DR: The proposed method was applied to the analysis of four different sources water samples and the relative recoveries of spiked water samples are 99.9-115.7% and 87.3-117.6% at three different concentration levels of 75, 200 and 1000 microg L(-1), respectively.
