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 ...

Recent developments of dispersive liquid-liquid microextraction technique
Chinese Journal of Chromatography, 2015As a relatively new sample preparation technique, dispersive liquid-liquid microextraction (DLLME) has the advantages of simplicity of operation, high enrichment factor and low consumption of organic solvent. In this review, the recent advances of DLLME and its important applications are briefly reviewed, including (1) the combined use of DLLME with ...

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

Automated Agitation-Assisted Demulsification Dispersive Liquid–Liquid Microextraction
Analytical Chemistry, 2016Dispersive liquid-liquid microextraction (DLLME) is an extremely fast and efficient sample preparation procedure. For its capability and applicability to be fully exploited, full automation of its operations seamlessly integrated with analysis is necessary. In this work, for the first time, fully automated agitation-assisted demulsification (AAD)-DLLME

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 ...
