Separation of Lithium from Liquid Media

Lithium ions are mono-valent cations and are generally sorbed by strong acid cation exchange resins.

Lithium, along with other cations, can be removed from water with a strong acid cation exchanger such as AmberSep™ G26 H Resin. However, since lithium has a very low affinity compared to most other cations, leakage from the resin will occur ahead of the more attracted ionic species in the matrix. Lithium can only be selectively removed as an aluminum complex as described in the provided references.1,2
