RT journal article T1 Advances in ionic liquids and deep eutectic solvents-based liquid phase microextraction of metals for sample preparation in Environmental Analytical Chemistry A1 Herce Sesa, Belén A1 López López, José Antonio A1 Moreno Aguilar, Carlos A2 Química Analítica K1 Ionic liquids K1 Deep eutectic solvents K1 Liquid-phase micro-extraction K1 Metals K1 Speciation K1 Environmental analysis AB Liquid phase micro-extraction (LPME) of metals has showed its potential for sample preparation inenvironmental analysis. In particular, the incorporation of ionic liquids to LPME (IL-LPME) has gottenincreasing interest due to their unique properties as organic salts liquid at room temperature. In the lastyears, IL-LPME of metals has evolved to more efficient and selective extraction methods thanks to thedevelopment of task specific ionic liquids, and deep eutectic solvents. ILs have been implemented in themain LPME modalities: SDME, DLLME and HFLPME, resulting in new versions of these techniques.In this review we have analyzed and discussed the latest developments done in IL-LPME of metals,their advantages and limitations, as well as the potential fields of future development.© 2021 The Author(s).
