- DLLME is a simple and fast microextraction technique, the major benefits of which are mainly (i) the negligible volumes (a few microliters only) of extraction solvents used;
- (ii) the very large surface area between the fine droplets of the extraction solvent and the aqueous sample, and the accordingly fast extraction kinetics that result in the rapid achieving of a state of equilibrium [15]; and (iii) the high enrichment factor usually obtained.
