Abstract: A magnetic titanium-based lithium adsorbent includes a magnetic composite and a lithium adsorption layer. The lithium adsorption layer is located on an outer surface of the magnetic composite. The magnetic composite includes a magnetic material and a titanium oxide. The lithium adsorption layer includes a lithium titanium oxide. A method for preparing the magnetic titanium-based lithium adsorbent includes the following steps: a magnetic composite is obtained; a precursor of the magnetic titanium-based lithium adsorbent is prepared; and pre-desorption is carried out.
