Simultaneous synthesis of a deep eutectic solvent and its application in liquid–liquid microextraction of polycyclic aromatic hydrocarbons from aqueous samples
TL;DR: In this paper, a new generation of solvents, named deep eutectic solvent, was simultaneously synthesized and used as an extraction solvent in a liquid-liquid microextraction method for the extraction and preconcentration of some polycyclic aromatic hydrocarbons from aqueous samples prior to their determination by high performance liquid chromatography-diode array detection.
