Systematic evaluation of hydrophobic deep eutectic solvents as alternative media for the extraction of metal ions from aqueous solution

Quantification of alkalinity of deep eutectic solvents based on (H−) and NMR

“…Because of these distinctive characteristics, alkaline DESs are an ideal choice as efficient green solvents. 27,28 Therefore, it is of great theoretical and industrial importance to explore suitable methods for describing the alkalinity of alkaline DESs. [29][30][31] The current exploration will assist in comprehending alkaline principles and designing more optimal alkaline DESs with excellent alkalinity and application prospects.…”

Understanding the excited state dynamics and redox behavior of highly luminescent and electrochemically active Eu(iii)–DES complex

“…Soldner et al 28 have utilized the emission characteristics of lanthanide ions for their separation using DES. Kaul et al 29 have utilized DES for the extraction of metal ions from the aqueous solution. Our group also worked extensively on exploring DES media for speciation studies and dissolution of rare earth and actinide ions.…”

Selective extraction of plant bioactive compounds with deep eutectic solvents: Iris sibirica L. as example

“…Cheap, accessible, and environmentally friendly compounds such as choline chloride, urea, glycerol (Glyc), ethylene glycol (EG), and fruit acids are often used as components of such solvents 25,26 . DESs have found wide application for the extraction of both organic and inorganic substances from various objects 27–31 . A number of compounds were extracted from plants using DESs, such as volatile substances, 32 alkaloids, 33 anthocyanins, 34 phenylpropanoids, 35 saponins, 36 vitamins, 37 and so on.…”

“…25,26 DESs have found wide application for the extraction of both organic and inorganic substances from various objects. [27][28][29][30][31] A number of compounds were extracted from plants using DESs, such as volatile substances, 32 alkaloids, 33 anthocyanins, 34 phenylpropanoids, 35 saponins, 36 vitamins, 37 and so on. Low saturated vapor pressure, low cost, biodegradability, compatibility with chromatographic detection methods, and high extraction ability have led to the widespread use of these solvents in the practice of analysing plant materials.…”
