Abstract
The demand for lithium is growing rapidly with the increase in electric vehicles, batteries and electronic equipments. Lithium can be extracted from brines, yet the separation of lithium ions Li+ from magnesium ions Mg2+ is challenging at high Mg/Li ratios. Here, we review methods to extract lithium from brines, such as extraction, adsorption, nanofiltration, selective electrodialysis and electrochemical intercalation/de-intercalation, with focus on the selective separation of lithium at high Mg/Li ratios. Extraction can be done with organic solvents and ionic liquids. Adsorption is performed with aluminum-, manganese- and titanate-based adsorbents.
期刊介绍：
Environmental Chemistry Letters explores the intersections of geology, chemistry, physics, and biology. Published articles are of paramount importance to the examination of both natural and engineered environments. The journal features original and review articles of exceptional significance, encompassing topics such as the characterization of natural and impacted environments, the behavior, prevention, treatment, and control of mineral, organic, and radioactive pollutants. It also delves into interfacial studies involving diverse media like soil, sediment, water, air, organisms, and food. Additionally, the journal covers green chemistry, environmentally friendly synthetic pathways, alternative fuels, ecotoxicology, risk assessment, environmental processes and modeling, environmental technologies, remediation and control, and environmental analytical chemistry using biomolecular tools and tracers.
