“…This type of DES have limited application toward nutraceuticals extraction but has been established with the lowest viscosity of all the other types. They are generally used for the extraction of dyes, heavy metals, synthetic pigments in foods, and quantitative determination of pharmaceutical drugs in human samples . Recent investigations have also employed these hydrophobic DES toward extraction of antibiotics. , …”

Deep eutectic solvents (DES) hold promising potential in the selective purification of bioactive molecules from various complex sources. Although they are increasingly considered as a biocompatible extraction medium, adding the task-specific functionality, which makes DES distinctive for the selective extraction of compounds, requires appropriate tailoring of their physical properties. This critical review investigates the influential physical properties of deep eutectic solvents and their effect on various sustainable extraction methodsincluding both solid–liquid and liquid–liquidfor the separation of nutraceuticals. Various methods by which DES are employed as solvents, cosolvents, or as adjuvants in different extraction systems are compared in terms of their efficiency and selectivity. Furthermore, the correspondence between the type of DES and the nature of target nutraceuticals to be extracted is also discussed. The Review highlights the key achievements and future prospects of employing DES along with the lacunae in the current investigations and proposed various approaches for sustainable applications.

Spent Li-ion battery (LIB) recovery has become the hot research area due to its surge in quantity and release of heavy metals and toxic substances harmful to the environment. Green and efficient recovery methods are of great significance for the recovery of valuable metals. Herein, an oxalic acid-based deep eutectic solvent (DES) with the weak acidic character and reducibility of oxalic acid was designed for the recovery of valuable metals from spent LIBs via a sustainable and convenient process. Nearly 96.1% of Li and 96.3% of Co can be extracted from lithium cobalt oxide at 120 °C. The DES can extract valuable metals from cathode materials and separate metal ions by itself after extraction without destroying its own structure in a one-pot extraction process. The composition and the structure of DES have been maximum retained and could be intact recycled for another recovery process. After five cycles, the Li and Co extraction efficiencies were maintained above 92.9 and 74.5%, respectively. This work provides a sustainable one-pot recovery process with inexpensive and simple operations for valuable metal recovery from spent LIBs.

“…Roldán-Ruiz et al 31 applied p -toluenesulfonic acid monohydrate/choline chloride (ChCl) H 2 O DES to leach Co in LCO, and the extraction efficiency exceeds 94%. Chen et al 42 reported a class of hydrophobic DESs (HDESs) formed from tetrabutylammonium chloride and oleic acid that can selectively extract Li + from the mother liquor with a high Na/Li ratio. To date, most research on DESs has focused only on the recycling of LCO batteries, which limits the broad application of DESs in the field of LIB recycling.…”

“…[29][30][31][32][33][34][35][36] DESs, first proposed by Abbott 37 in 2003, are a class of low eutectic mixtures comprising a combination of a hydrogen-bond acceptor (HBA) and a hydrogen-bond donor (HBD) through intermolecular hydrogen bonding, and have a melting point lower than that of either constituent.
