Aluminum Chloride Granular Adsorbent for Lithium Recovery

Technical Background   Aluminum‑based lithium adsorbents (chemical formula LiCl·2Al(OH)₃·nH₂O) are among the most widely used adsorption materials for industrial lithium extraction from salt lakes. These adsorbents achieve selective lithium adsorption through the reversible intercalation and deintercalation of lithium ions within the layered double hydroxide (LDH) structure. The adsorption mechanism involves lithium ions intercalating into the interlayer spaces of the adsorbent, undergoing ion exchange with hydrogen ions, with no significant change in crystal structure before and after adsorption. As the core aluminum source for these adsorbents, Aluminum Chloride Hexahydrate directly determines the adsorbent‘s adsorption capacity, selectivity, and cycle life through its purity, impurity content, and batch‑to‑batch consistency.   Key Quality Specifications   Parameter Specification Impact on Adsorbent Performance Aluminum Chloride Hexahydrate (AlCl₃·6H₂O) > 93.0% Ensures sufficient…
