- Abstract
- The growing interest in the use of lithium in electrochemical energy contributes to the development of methods for its extraction from various sources, including geothermal and reservoir brines. The article summarizes current information about effective sorbents for the extraction of lithium ions from aqueous solutions and natural brines. In the last 10-15 years, intercalation-type sorbents based on aluminum hydroxide, manganese and titanium oxides have been in high demand for the selective extraction of lithium. Sorbents based on manganese oxides and titanium oxides demonstrate higher sorption capacities when extracting lithium from aqueous solutions. However, the practical application of such sorbents is limited by operating costs and use cycles. Numerous studies have shown that aluminum hydroxide sorbents are suitable for lithium extraction from seawater, salt lakes, and geothermal brine solutions, but their large-scale industrial use has yet to be established. In the case of other materials, such as organic ion exchangers or zeolites, they generally have low selectivity for lithium ions, which is impractical in the practical extraction of a valuable component.
