Abstract: In order to resolve the problem that a magnetic lithium adsorbent in the related art is difficult to be used for lithium extraction from strong-alkaline and carbonate-type brines, a magnetic titanium-based lithium adsorbent is provided, which includes a magnetic composite and a lithium adsorption layer. The lithium adsorption layer is disposed at 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.
