Aluminum-based Lithium Adsorbent

Features of the Aluminum-based Lithium Adsorbent:

High Selectivity：The adsorbent exhibits a high level of selectivity for lithium ions, capable of effectively separating lithium from the complex salt lake brine or other lithium-containing solutions. It has a relatively lower adsorption capacity for other common ions such as sodium, potassium, and magnesium, which contributes to enhancing the purity of lithium extraction.

Large Adsorption Capacity: It can adsorb a significant amount of lithium ions, with a high adsorption capacity that meets the demand for large-scale lithium extraction, thereby increasing the efficiency of lithium extraction to some extent.

Good Stability: The adsorbent possesses excellent chemical and thermal stability, maintaining structural and performance stability under complex environmental conditions such as the salt lake brine, without easy decomposition or deterioration. It has strong reusability and a long service life.

Environmentally Friendly: In the process of lithium extraction from brines, it generally does not require the use of large amounts of acids, bases, or other reagents, resulting in minimal environmental pollution and meeting green and environmentally friendly requirements.

Good Recycling Performance: After cycles of adsorption and desorption, the adsorbent can still maintain good adsorption performance with minimal changes in adsorption capacity and selectivity, which is beneficial for reducing the cost of lithium extraction.

Broad Applicability: It is not only suitable for lithium extraction from the salt lake brine with high magnesium to lithium ratios but also has potential applications for other lithium-containing solutions such as seawater and underground brines.
