In this work, a natural deep eutectic solvent (NADES) composed of l-menthol:acetic acid 1:1 (molar ratio) was applied for the first time as the extraction solvent for the dispersive liquid–liquid microextraction (DLLME) of a group of 9 phthalic acid esters (i.e., dipropyl phthalate, DPP; butyl benzyl phthalate, BBP; dibutyl phthalate, DBP; diisopentyl phthalate, DIPP; di-n-pentyl phthalate, DNPP; dicyclohexyl phthalate, DCHP; di(2-ethylhexyl) phthalate, DEHP; diisononyl phthalate, DINP; and diisodecyl phthalate, DIDP) from different water samples (i.e., tap and mineral water) and an apple juice beverage. Dihexyl phthalate (DHP) and di-n-octyl phthalate (DNOP) were used as internal standards. After addition of the DES, agitation, and centrifugation, the NADES droplet was collected, dissolved in the mobile phase, and injected in a high-performance liquid chromatograph coupled to a UV detector. Relative recovery percentages were in the range 71–120% with relative standard deviation values ≤20%, while the limits of quantification of the method were in the range 3.6–22 μg/L for tap water, 3.8–20 μg/L for mineral water, and 4.0–23 μg/L for an apple juice drink. Infrared spectroscopy and differential scanning calorimetry analysis of the DES drop after the DLLME procedure revealed the absence of the DES after the extraction and the existence of an l-menthol-rich phase as a result of an important transfer of acetic acid to the aqueous phase. However, the use of l-menthol alone, which required the previous thermal solubilization of l-menthol, was not able to quantitatively extract some of the target analytes. The extraction carried out after the thermal solubilization of l-menthol and the addition of an acid like HCl suggested that the extraction capacity of the DES is caused by a “transient network” originated by the acidity of the medium, independently of the nature of the acid. The optimized NADES-DLLME procedure was extremely simple, quick, and also environmentally friendly, as a result of the biodegradability and relatively low toxicity of both components of the DES.

“…Many methods have been developed to assist the extraction process, such as vortex, heating, microwave, and ultrasonic. Some studies made the methods more convenient and faster by reducing the number of steps, such as the synthesis of DESs [49,50]. At the same time, in order to more thoroughly separate the organic phase and the water sample, researchers made the extractant magnetic and combined it with LPME [51].…”

Water sources are an indispensable resource for human survival. Monitoring the pollution status of the surrounding environment is necessary to protect water sources. Research on the environmental matrix of deep eutectic solvents (DESs) has expanded rapidly because of their high extraction efficiency for various target analytes, controllable synthesis, and versatile structure. Following the synthesis of hydrophobic deep eutectic solvents (HDESs), their application in aqueous matrices broadened greatly. The present review conducted a survey on the pollutant extraction methods based DESs in environmental matrices from two aspects, application methods and matrix types; discussed the potential risk of DESs to the environment and future development trends; and provided some references for researchers to choose DES-based extraction methods for environmental research.

“…Recently, menthol-decanoic acid DESs are more favored by scientific workers thanks to their natural low toxicity, high compatibility with instruments [20], and almost no loss of quality in the extraction system [21]. Moreover, these DESs are used in detection of various environmental pollutants such as benzophenone-type UV filters [22], parabens [23], antidepressants [19], and polycyclic aromatic hydrocarbons [24]. Unfortunately, the application of mentholdecanoic acid DESs for fungicide detection has not been reported yet.…”

An ecofriendly and efficient ultrasound-assisted deep eutectic solvents dispersive liquid-phase microextraction by solidifying the deep eutectic solvents-rich phase was developed to determine azoxystrobin, fludioxonil, epoxiconazole, cyprodinil, and prochloraz in fruit juices and tea drinks by high-performance liquid chromatography. A varieties of environmental hydrophobic deep eutectic solvents serving as extraction agents were prepared using L-menthol and decanoic acid as hydrogen-bond acceptor and hydrogen-bond donor, respectively. The deep eutectic solvents were ultrasonically dispersed in sample solutions, solidified in a freezer and easily harvested. The main variables were optimized by one-factorat-a-time and response surface test. The new method performs well with relative recovery of 71.75-109.40%, linear range of 2.5-5000 μg/L (r ≥ 0.9968), detection limit of 0.75-8.45 μg/L, quantification limit of 2.5-25 μg/L, , and inter-and intraday relative standard deviations below 13.53 and 14.84%, respectively. As for the extraction mechanism, deep eutectic solvents were disposed into many fine particles in the solution and captured the analytes based on the changes of particle size and quantity in deep eutectic solvents droplets after extraction. The environmental method can successfully detect fungicide residues in real fruit juices and tea drinks.
