The titanium lithium ion sieve（HTO） was synthesized via high temperature solid state method by using amorphous hydrated titanium dioxide and lithium hydroxide as the titanium source and lithium source,respectively.And the scanning electron microscopy（SEM）,X-ray diffraction（XRD） and contact angle test were further carried out.The effect of HTO in salt lake brine with high n（Mg）/n（Li） over time on the lithium adsorption capacity was studied.The results showed that the adsorption capacity of HTO in salt lake brine with high n（Mg）/n（Li）reached 24.8 mg/g for 26 h.HTO had excellent selectivity with separation coefficient（αLi Mg） of 4 813.0.After 20 adsorption cycle tests,the lithium adsorption capacity of HTO decrea-sed by only 4.8%,and the dissolution rate of titanium was below 0.08% each time.The results showed that HTO had good cyclic adsorption performance and stability.The HTO had the ability to extract lithium from salt lake brine with high n（Mg）/n（Li）,and showed very broad market prospect.
