Extraction and determination of 2-pyrazoline derivatives using liquid phase microextraction based on solidification of floating organic drop

A simple, rapid and efficient microextraction method for the extraction and determination of some 2-pyrazoline derivative compounds in aqueous samples was developed. Microliter volumes of 1-undecanol were delivered to the surface of the aqueous sample and the sample was agitated for a desire time…
