Abstract: A method for lithium adsorption in a carbonate- and/or sulfate-containing solution, comprising using an aluminum-based lithium adsorbent for adsorption of lithium ions in the carbonate- and/or sulfate-containing solution, after the adsorption is saturated, using a weakly acidic high-concentration salt solution to transform the adsorbent, desorbing the transformed adsorbent by means of a low-concentration salt solution or water, and entering the next cycle for operation.
