“…Dispersive liquid−liquid microextraction with hydrophobic DESs controlled by freezing temperature was also investigated. 16 Basically, floating organic droplets were solidified during the dispersive liquid−liquid microextraction, after which high performance liquid chromatography was used for determining the benzoylureas in the water phase. The benzoylureas that were investigated are triflumuron, hexaflumuron, flufenoxuron, and lufenuron.…”

“…In 2016, still only a few papers were presented, but the very impressive work on the removal of metals from an aqueous environment was started. , The year 2017 was really a year of growth for the hydrophobic DES field. Some very interesting applications that were investigated include the extraction of Artemisinin, a medicine for malaria, from Artemisia annua leaves, the first microextractions, photon upconversion, and the use of hydrophobic DESs in membranes . In the years after, a rapid growth of the field was observed.…”

Hydrophobic deep eutectic solvents (DESs) are a new generation of water immiscible solvents that have been presented in the literature for the first time in 2015. These solvents have been used for many applications. Here, an overview is given regarding hydrophobic DESs with their physicochemical properties, applications, and the challenges and limitations that the field currently is experiencing. First, a general introduction and an introduction to hydrophobic DESs are presented to explain more about DESs, their origin, and hydrophobic ones. Here, also, an overview of all the hydrophobic DESs presented in the literature is given. After the introduction, physicochemical properties such as density, viscosity, melting point, degradation temperature, volatilities, and solvatochromic properties are discussed. It is continued with the discussion of 21 different applications of hydrophobic DESs. In general, applications related to liquid–liquid extractions, liquid–liquid microextractions, formation of two and three phase systems, removal of components from leaves, gas–liquid extractions, formation of hydrogels, membrane formation, centrifugal partition chromatography, formation of a ferrofluid, coating, photoluminescence, and dye-sensitized solar cells, and catalysis have been investigated. Finally, challenges and limitations of hydrophobic DESs are discussed.

Preparing a sample for analysis is a crucial step of many analytical procedures. The goal of sample preparation is to provide a representative, homogenous sample that is free of interferences and compatible with the intended analytical method. Green approaches to sample preparation require that the consumption of hazardous organic solvents and energy be minimized or even eliminated in the analytical process. While no sample preparation is clearly the most environmentally friendly approach, complete elimination of this step is not always practical. In such cases, the extraction techniques which use low amounts of solvents or no solvents are considered ideal alternatives. This paper presents an overview of green extraction procedures and sample preparation methodologies, briefly introduces their theoretical principles, and describes the recent developments in food, pharmaceutical, environmental and bioanalytical chemistry applications.

“…DES ([N8,8,8,1]Cl: 1-dodecanol, 1:1) was used as the extracting solvent for the preconcentration of benzoylureas from water samples prior to HPLC analysis. Good recoveries in the range of 82–93% with high precision (%RSD < 5%) and high EFs for the analytes (91–97) were achieved [ 40 ]. Furthermore, the viscosity of the DESs decreased as the quaternary ammonium chain decreased.…”

Deep eutectic solvents (DESs) have recently attracted attention as a promising green alternative to conventional hazardous solvents by virtue of their simple preparation, low cost, and biodegradability. Even though the application of DESs in analytical chemistry is still in its early stages, the number of publications on this topic is growing. Analytical procedures applying dispersive liquid–liquid microextraction based on the solidification of floating organic droplets (DLLME-SFOD) are among the more appealing approaches where DESs have been found to be applicable. Herein, we provide a summary of the articles that are concerned with the application of DESs in the DLLME-SFOD of target analytes from diverse samples to provide up-to-date knowledge in this area. In addition, the major variables influencing enrichment efficiency and the microextraction mechanism are fully investigated and explained. Finally, the challenges and future perspectives of applying DESs in DLLME-SFOD are thoroughly discussed and are critically analyzed.
