The boosted interest in using rare earth elements (REEs) in modern technologies has also increased the necessity of their recovery from various sources, including raw materials and wastes. Though hydrometallurgy plays a key role in these recovery processes, some drawbacks (apparent or not) of these processes (including the use of aggressive mineral acids, harmful extractants, and diluents, etc.) have led to the development of an environmental friendship subclass named solvometallurgy, in which non-aqueous solvents substituted to the aqueous media of the hydrometallurgical processing. Together with ionic liquids (ILs), the non-aqueous solvents chosen for these usages are the chemicals known as deep eutectic solvents (DEEs). The utilization of DEEs included the leaching of REEs from the different sources containing them and also in the separation-purification steps necessary for yielding these elements, normally oxides or salts, in the most purified form. This work reviewed the most recent literature (2023 year) about using deep eutectic solvents to recover REEs from various sources and coupling these two (DESs and REEs) to derive compounds to be used in other fields.

This study introduces a technique for decontaminating radioactive surfaces by employing a gel, herein termed as radiation decontamination gel with eutectic liquids (RADGEL), composed of a deep eutectic solvent and polyvinyl alcohol, with the goal of enabling reuse of the surface post‐decontamination. The decontamination effectiveness of RADGEL underwent thorough evaluation through trials conducted on different simulated surfaces, achieving decontamination efficiency up to 99.9% for alpha as well as gamma radionuclides. The various parameters influencing decontamination factors such as amount of complexing agent used, polymer film thickness, nature, and magnitude of radioactivity, as well as surface characteristics of substrates to be decontaminated were optimized. Additionally excellent mechanical strength of RADGEL, affirms its potential as practically efficient, cost‐effective, and safe option for surface decontamination. The Fourier‐transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM) analysis suggest RADGELs capability for both physical and chemical interactions with contaminants, thus highlighting its comprehensive decontamination efficacy. The outcomes of this study carry substantial implications for the decontamination of surfaces contaminated with various types of radionuclides.
