Classification and terminology in dispersive liquid–liquid microextraction
Microchemical Journal, 2016Abstract The literature on dispersive solvent microextraction comprises a great many methodologies, different possibilities and a broad range of terminology, all of which greatly complicates the classification of these methods as well as the conditions to be specified in the procedure name, its acronym or both.

Extensible automated dispersive liquid–liquid microextraction
Analytica Chimica Acta, 2015In this study, a convenient and extensible automated ionic liquid-based in situ dispersive liquid-liquid microextraction (automated IL-based in situ DLLME) was developed. 1-Octyl-3-methylimidazolium bis[(trifluoromethane)sulfonyl]imide ([C8MIM]NTf2) is formed through the reaction between [C8MIM]Cl and lithium bis[(trifluoromethane)sulfonyl]imide ...

Evolution of dispersive liquid–liquid microextraction method
Journal of Chromatography A, 2010Dispersive liquid-liquid microextraction (DLLME) has become a very popular environmentally benign sample-preparation technique, because it is fast, inexpensive, easy to operate with a high enrichment factor and consumes low volume of organic solvent. DLLME is a modified solvent extraction method in which acceptor-to-donor phase ratio is greatly reduced

Recent developments in dispersive liquid–liquid microextraction
Analytical and Bioanalytical Chemistry, 2013During the past 7 years and since the introduction of dispersive liquid-liquid microextraction (DLLME), the method has gained widespread acceptance as a simple, fast, and miniaturized sample preparation technique. Owing to its simplicity of operation, rapidity, low cost, high recovery, and low consumption of organic solvents and reagents, it has been ...

Dispersive liquid–liquid microextraction using a surfactant as disperser agent
Analytical and Bioanalytical Chemistry, 2010A novel and efficient surfactant-assisted dispersive liquid-liquid microextraction combined with high-performance liquid chromatography-photodiode array detection was developed for the determination of phenylurea herbicides in water samples. Based on this procedure, which is a dispersive-solvent-free technique, the extractant is dispersed in the ...

Solvent-terminated dispersive liquid-liquid microextraction: a tutorial
Analytica Chimica Acta, 2018Solvent-terminated dispersive liquid-liquid microextraction (ST-DLLME) is a special mode of DLLME in which a demulsifying solvent is injected into the cloudy mixture of sample/extractant to break the emulsion and induce phase separation. The demulsification process starts by flocculation of the dispersed microdroplets by Ostwald ripening or coalescence

Pharmaceutical and biomedical applications of dispersive liquid–liquid microextraction
Journal of Chromatography B, 2017Sample treatment is so crucial in pharmaceutical and biomedical analysis. Proper sample preparation protects the analytical instrument, increases the sensitivity, and enhances the selectivity by removing probable interfering substances. Dispersive liquid-liquid microextraction (DLLME) is one of the most important approaches in sample treatment.

Automated in-syringe dispersive liquid-liquid microextraction
TrAC Trends in Analytical Chemistry, 2014Abstract The dispersive liquid-liquid microextraction (DLLME) technique is simple, efficient and environment friendly. One of the main limitations to its further development is the lack of approaches to its automation. In this work, we describe and review recent applications of a novel approach to perform fully-automated in-syringe DLLME based on ...
