摘要

随着电动汽车、电池和电子设备的增加，对锂的需求正在迅速增长。锂可以从盐水中提取，但在高Mg/Li比下，锂离子Li+和镁离子Mg2+的分离是具有挑战性的。本文综述了萃取法、吸附法、纳滤法、选择性电渗析法和电化学插/脱插法等从盐水中提取锂的方法，重点介绍了高Mg/Li比下锂的选择性分离方法。萃取可以用有机溶剂和离子液体进行。用铝、锰和钛酸盐基吸附剂进行吸附。

Lithium extraction from salt lake brines with high magnesium/lithium ratio: a review

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.
