In this paper,titanium dioxide(TiO2)and lithium carbonate(Li2CO3)were used as titanium sources and lithium sources,and the titanium lithium ion screen precursor Li2TiO3(LTO)was prepared by high temperature solid phase method.The precursor LTO was acid-washed with HCl,and the titanium lithium ion screen H2TiO3(HTO)was obtained after exchange between Li+ and H+.The structure and morphology of titanium lithium ion screen were characterized by XRD and SEM.The effects of calcination temperature,pickling concentration,pickling temperature and pickling time on the adsorption properties of titanium lithium ion screen were investigated.The experimental results showed that LTO was prepared by calcination at 850℃for 10 h.The HTO adsorbent can be prepared by pickling LTO at 80℃with 0.20 mol/L HCl solution for 6 h.The adsorption capacity(Qe)of HTO adsorbent for lithium ions in solution was up to 28.83 mg/g.
