Recent advances in liquid-phase microextraction techniques for the analysis of environmental pollutants

Recent advances in liquid-phase microextraction techniques for the analysis of environmental pollutants
The liquid phase microextraction method is a sample pretreatment technique that uses small volumes of organic solvents to extract a wide variety of analytes from different matrices prior to instrumental analysis. The development of these techniques focuses on providing simple, inexpensive, and environmentally friendly extraction procedures for sample preparation. In this review, the most recent developments in liquid-phase microextraction (LPME) techniques for the analysis of various environmental pollutants are summarized. These methods have been categorized into several groups including dispersive liquid-liquid microextraction (DLLME), ferrofluid-based microextraction, supramolecular-based liquid phase microextraction, and vortex-assisted liquid-liquid microextraction. In this paper, the extraction principles, the solvent production mechanism, and the historical development of the LPME techniques are discussed. Finally, recent reports on the applications of these methodologies are reviewed.
