“…However, due to the high viscosity of ionic liquids and difficultly in dissolving the crown ether in imidazolium-based ionic liquids, the traditional organic solvent is usually added as a diluent to the extraction solvent. [22] Liu et al [32] investigated the lithium isotope effects on extraction and separation using 4-aminobenzo-15-crown-5 (4-AB) as the extractant and ionic liquid and anisole as solvent and diluent, respectively. The lithium salt was extracted from the aqueous phase into the organic phase using extremely concentrated crown ether to generate the Li þ (crown) 2 complex.…”

The ability to generate materials with an enriched isotopic abundance, that is one that differs from natural abundance, is critical in terms of technology. Isotopes are used in a wide range of applications, including radioactive tracers, nondestructive tests, radiotherapy in human medicine, nuclear fuels, and isotope-substituted compounds for chemistry and biology research, as well as environmental geochemical signature tracers. A commonly discussed research topic is the isotopic separation of various elements-uranium, hydrogen, lithium, and iodine, among many others. Among these isotopes, lithium isotopes are especially important in various applications including strategic areas. These isotopes are light and hence their separation techniques are not very obvious. Herein, all the main categories of Li isotope separation are reviewed in depth with a focus on electrochemical technologies for stable lithium isotope separation.
