Deep eutectic solvents provide a sustainable and efficient hydrometallurgical route for selective metal leaching from discarded circuit boards. This review outlines DES synthesis, key properties, and their environmental and economic advantages.
This study explores the impact of water on the molecular arrangement of reline and ethaline deep eutectic solvents (DESs) across varying concentrations ranging from 26 to 78 wt%.
Immobilization of eutectic mixtures in supramolecular gels formed using low molecular weight gelators is a smart strategy to expand their design space. Advances in the last five years are reviewed from the viewpoint of sustainability.
Computational analyses were carried out on solubilization of the heteroaromatic drugs allopurinol, losartan, and omeprazole in reline, a deep eutectic solvent (DES) composed of choline chloride/urea in 1 : 2 molar ratio.
The potential of hydrophobic type V DESs for the liquid–liquid separation of metal ions is reviewed along with the properties relevant to their application and their potential advantages and limitations compared to conventional solvent extraction.
