“…By growing Fe 3 O 4 on lithium manganese oxides (LMOs) with different Li precursor contents, the final composed ion sieve was proved to be non-toxic, low cost, and easy to synthesize. Among the various previously reported ion sieves [116], magnetic H 1.33 Mn 1.66 O 1.67 exhibited optimal Li ? selectivity and chemical stability, with an adsorption capacity of 6.84 mg/g in LiCl buffer solution and 12.2 mg/g in concentrated seawater under harsh conditions.…”

Rapid developments in the electric industry have promoted an increasing demand for lithium resources. Lithium in salt lake brines has emerged as the main source for industrial lithium extraction, owing to its low cost and extensive reserves. The effective separation of Mg 2? and Li ? is critical to achieving high recovery efficiency and purity of the final lithium product. This paper summarizes Mg 2? /Li ? separation materials and methods in the field of lithium recovery from salt lake brines. The review begins with an introduction to the global distribution and demand for lithium resources, followed by a description of the materials used in various separation techniques, including precipitation, adsorption, solvent extraction, nanofiltration membrane, electrodialysis, and electrochemical methods. A comparison, analysis, and outlook of such methods are comprehensively discussed in terms of principles, mechanisms, synthesis/operation, development, and industrial applications. We conclude with a presentation of challenges and insights into the future directions of lithium extraction from salt lake brines. A combination of the advantages of various materials is the most logical step toward developing novel methods for extracting lithium from brines with high separation selectivity, stability, low cost, and environmentally friendly characteristics.

The lithium titanium oxide ion sieve with good structural stability and high adsorption capacity is generally considered to be a promising adsorbent for lithium recovery. Herein, the lithium ion sieve precursor Li2TiO3 was prepared based on amorphous TiO2, and then Li+ was acid‐eluted to obtain the lithium adsorbent H2TiO3, denoted as HTO‐Am. The structure and adsorption properties of HTO‐Am were investigated, and the results demonstrated that the HTO‐Am prepared at the optimum temperature had excellent adsorption properties for Li+. The adsorption process follows pseudo‐second‐order kinetic and Langmuir isotherm equations, indicating that lithium is adsorbed chemically and monolayer on HTO‐Am. HTO‐Am ion sieves were prepared successfully for the first time and exhibited high selectivity, favorable adsorption rate, and cycle performance for Li+.

“…Several adsorbents such as lithium manganese oxides (LMOS), ion sieves, H 2 TiO 3 [10], and ion-imprinted polymers [11] have been prepared for the adsorption of lithium. Among them, the most common inorganic adsorbents are the LMOS [12][13][14] and ion sieves, which have good adsorption capacities and selectivities [15]. However, these adsorbents with powder forms cannot be practically used due to the loss of adsorbents in their applications [16,17].…”

The separation of Li+ from an aqueous solution has received much attention in recent years because of its wide application in batteries and nuclear energy. A cellulose microsphere adsorbent with sulfonic acid groups (named as CGS) was successfully prepared by the pre-irradiation-induced emulsion graft polymerization of glycidyl methacrylate onto cellulose microspheres through subsequent sulfonation and protonation. The adsorption performance of Li+ onto the CGS adsorbent is investigated in detail. The as-prepared CGS adsorbent exhibited fast adsorption kinetics and a high adsorption capacity of Li+ (16.0 mg/g) in a wide pH range from 4 to 10. The existence of K+ and Na+ was found to have the ability to affect the adsorption capacity of Li+ due to the cation-exchange adsorption mechanism, which was further confirmed by X-ray photoelectron spectroscopy (XPS). The column adsorption experiment indicated that the adsorption capacity of CGS agreed well with the batch adsorption, and a fast desorption could be obtained in 10 min. It is expected that CGS has potential usage in the adsorption separation of Li+ from an aqueous solution.
