Abstract: The precursor of Ce-doped titanium ion sieve was synthesized via a high temperature solid phase method using titanium dioxide, lithium carbonate and cerium nitrate hexahydrate as raw materials. Ce-doped titanium ion sieve (HTO-Ce) was obtained after acid washing. Adsorption performance was evaluated by XRD, SEM and XPS. The results show that the ion sieve cell structure is improved after Ce doping, and the Li⁺ exchange efficiency is obviously promoted. The saturation capacity of HTO-Ce for Li⁺ was 32.53 mg⋅g⁻¹, which was increased by 9.4% compared with the unmodified. Satisfying adsorption effects can be achieved at room temperature and pH=8 after 20 cycles. Adsorption rates of Li⁺ stayed over 80% and its crystal structure remained the same because of high stability. The prepared material has application prospects in lithium extraction from salt lakes.
