中文摘要

溶剂萃取作为一种分离和纯化技术，在关键金属冶金中至关重要。溶剂萃取中常用的有机溶剂具有高挥发性、高毒性和易燃性等缺点，对人类健康和环境安全造成了一系列危害。新型溶剂被认为是这些有害有机溶剂的潜在替代品。在过去二十年里，人们提出了几种新型溶剂，包括离子液体（ILs）和深共晶溶剂（DESs）。DESs具有毒性低、可降解、成本低等优点，已逐渐成为绿色溶剂的焦点。本综述根据最新研究进展，系统地阐述了DESs的分类、形成机理、制备方法、表征技术和特殊物化性质。随后，全面总结了DESs在关键金属冶金中的分离和纯化应用。最后，探讨了DESs在当前研究领域的未来机遇和挑战。为提高对DESs的整体认识提供了宝贵的见解，并在扩大关键金属冶金中的分离和纯化应用方面具有重要潜力。

Abstract

Abstract

Solvent extraction, a separation and purification technology, is crucial in critical metal metallurgy. Organic solvents commonly used in solvent extraction exhibit disadvantages, such as high volatility, high toxicity, and flammability, causing a spectrum of hazards to human health and environmental safety. Neoteric solvents have been recognized as potential alternatives to these harmful organic solvents. In the past two decades, several neoteric solvents have been proposed, including ionic liquids (ILs) and deep eutectic solvents (DESs). DESs have gradually become the focus of green solvents owing to several advantages, namely, low toxicity, degradability, and low cost. In this critical review, their classification, formation mechanisms, preparation methods, characterization technologies, and special physicochemical properties based on the most recent advancements in research have been systematically described. Subsequently, the major separation and purification applications of DESs in critical metal metallurgy were comprehensively summarized. Finally, future opportunities and challenges of DESs were explored in the current research area. In conclusion, this review provides valuable insights for improving our overall understanding of DESs, and it holds important potential for expanding separation and purification applications in critical metal metallurgy.
