Efficient recovery of metals from secondary resources is essential to address resource shortages and environmental crises. The development of a cheap, environmentally friendly, and highly efficient recovery pathway is essential for resource retrieval. In this study, we propose a high-efficiency extraction approach utilizing bis(2,4,4-trimethylpentyl) phosphonic acid (Cyanex272) to recover cobalt from waste choline chloride/ethylene glycol (Ethaline) electrolyte containing Co(II) ions.

For many technological processes, the impact of water addition on the properties of deep eutectic solvents is of central importance. In this context, the impact of hydration on the reorientational dynamics of the deep eutectic solvent (DES) ethaline, a 2:1 molar mixture of ethylene glycol and choline chloride, was studied. Its overall response was explored by means of shear mechanical rheology.

Article Synopsis
- - Deep eutectic solvents (DES) are eco-friendly, low-cost solvents distinguished by their biodegradability, non-volatility, and non-toxicity, attracting increasing research interest.
- - A new ternary deep eutectic solvent (TDES) was developed using ethaline and glycine, with carboxylic acids added, and its properties were analyzed through techniques like FTIR and thermal stability assessments.
- - The study found that adding carboxylic acids improved the physical properties of the DES, such as viscosity and density, while also reducing surface tension, indicating significant interactions and bonding within the solvent system.

Electropolishing is a widely used technique for polishing additive manufactured (AM) components, while complex internal surface polishing remains a challenge. In this study, we explore the use of ethaline as an electrolyte and investigate the effects of temperature, time, stirring speed, and voltage on the electropolishing effectiveness for AM tubes without pre-treatment through orthogonal experiments. The optimal combination of these factors is then applied in further electropolishing experiments on straight tubes with large length-to-diameter ratios and an angled tube.

Deep eutectic solvents (DESs) were considered as a potential electrolyte because of their low price, harmless to environment and wider electrochemical window potential compared to water. In this work, Fe(III)/Fe(II) and Zn(II)/Zn redox couples were used as the positive and negative active materials, respectively, in a DES system using choline chloride and ethylene glycol in a molar ratio of 1 : 2 (ethaline). The possible working mechanism of the battery was studied by cyclic voltammetry, spectroscopic and simulation methods.
