“…Hence, hydrophobic DESs were sought after when extractions from aqueous streams are aimed at and found by, among others, van Osch et al [44], who used high-molecular weight carboxylic acids; Gilmore et al [45] and Schaeffer et al [46], who used trioctylphosphine oxide (TOPO); Cañadas et al [47] who used high-molecular amines; and Abranches et al [48], who demonstrated an unusually strong interaction between aromatic and aliphatic hydroxyl groups and defined this as a type V non-ionic DES. The hydrophobic DESs described by van Osch et al [44] have been studied in liquid-liquid extractions [44,49,50], and hydrophobic DESs, in general, have been applied to remove riboflavin [51], chlorophenols [52], caffeine [53], tryptophan [53], vanillin [53], isophthalic acid [53], platinum group and transition metals [45,46], phenolic antioxidants [47], and polycyclic aromatic hydrocarbons [54] from water.…”

Hydrophobic Deep Eutectic Solvents for the Recovery of Bio-Based Chemicals: Solid–Liquid Equilibria and Liquid–Liquid Extraction

The solid–liquid equilibrium (SLE) behavior and liquid–liquid extraction (LLX) abilities of deep eutectic solvents (DESs) containing (a) thymol and L-menthol, and (b) trioctylphosphine oxide (TOPO) and L-menthol were evaluated. The distribution coefficients (KD) were determined for the solutes relevant for two biorefinery cases, including formic acid, levulinic acid, furfural, acetic acid, propionic acid, butyric acid, and L-lactic acid. Overall, for both cases, an increasing KD was observed for both DESs for acids increasing in size and thus hydrophobicity. Furfural, being the most hydrophobic, was seen to extract the highest KD (for DES (a) 14.2 ± 2.2 and (b) 4.1 ± 0.3), and the KD of lactic acid was small, independent of the DESs (DES (a) 0.5 ± 0.07 and DES (b) 0.4 ± 0.05). The KD of the acids for the TOPO and L-menthol DES were in similar ranges as for traditional TOPO-containing composite solvents, while for the thymol/L-menthol DES, in the absence of the Lewis base functionality, a smaller KD was observed. The selectivity of formic acid and levulinic acid separation was different for the two DESs investigated because of the acid–base interaction of the phosphine group. The thymol and L-menthol DES was selective towards levulinic acid (Sij = 9.3 ± 0.10, and the TOPO and L-menthol DES was selective towards FA (Sij = 2.1 ± 0.28).

“…DES can be produced with two compounds, one being a hydrogen bond acceptor (HBA) and the other a donor (HBD), and these materials can be biodegradable. Due to these properties, DES have been explored as extraction media in another alternative for the development of greener methods [141]. The use of these solvents for BPA determination was successfully reported by several authors [92][93][94][95].…”

Bisphenol A is a synthetic compound widely used in industry, in the production of polycarbonate, epoxy resins, and thermal paper, among others. Its annual production is estimated at millions of tons per year, demonstrating its importance. Despite its wide application in various everyday products, once in the environment (due to its disposal or leaching), it has high toxicity to humans and animal life, and this problem has been well known for years. Given this problem, many researchers seek alternatives for its monitoring in matrices such as natural water, waste, food, and biological matrices. For this, new advanced materials have been developed, characterized, and applied in creative ways for the preparation of samples for the determination of bisphenol A. This article aims to present some of these important and recent applications, describing the use of molecularly imprinted polymers, metal and covalent organic frameworks, ionic liquids and magnetic ionic liquids, and deep eutectic solvents as creative solutions in sample preparation for the long-standing problem of bisphenol A determination.

“…This type of DESs is water-soluble, limiting its application to water-containing samples. Therefore, the development of hydrophobic DESs is highly desirable [53]. Faraji et al utilized a hydrophobic DES composed of tetrabutylammonium chloride and octanoic acid (1:2 M ratio) as a micro-extraction solvent coupled with HPLC analysis to extract and determine synthetic pigments, including lemon yellow, amaranth, sunset yellow, indigo, carmine, allura red, brilliant blue, and erythrosine [54].…”

Deep eutectic solvents (DESs) have emerged recently as new and green solvents. DESs can be used for extraction and separation of both inorganic metallic components and organic compounds such as phenolic compounds, flavonoids, sugars, and aromatic amines from food samples. DESs possess a tunable property simply by adjusting the ratio of hydrogen bond acceptors to the hydrogen bond donors. As a green extraction medium, DESs have various applications in the pretreatment process and improve the efficiency of different food analyses. This review summarizes the findings of recent studies on the development, production, application, and efficacy of DESs in the pretreatment process of various food analyses.
