Method for lithium adsorption in carbonate- and/or sulfate-containing solution

A lithium adsorption method in a carbonate-containing solution and/or a sulfate-containing solution, wherein the lithium adsorption method comprises:

• adsorbing lithium ions in a carbonate-containing solution and/or a sulfate-containing solution with an aluminum-based lithium adsorbent;
• then transforming the saturated adsorbent with a weakly acidic high concentration salt solution;
• and finally, restoring the adsorption performance of the adsorbent by using a low concentration salt solution or water for desorption, and entering the next cycle of operation.
