摘要：

The unusual selectivity for lithium ions shown by titanium(IV) antimonate cation exchanger (TiSbA) can be successfully applied for the recovery of lithium ions from seawater and hydrothermal water. The effects of the presence of other ions such as those of potassium, calcium and magnesium on the adsorption of lithium ions on TiSbA were investigated by a batch technique. The lithium adsorption decreased significantly with increasing the concentrations of K** plus , Mg**2** plus and Ca**2** plus . The presence of silica has no effect on the adsorption of lithium from hydrothermal water. The enrichment of lithium ions from seawater and hydrothermal water was carried out on TiSbA columns. Adsorbed lithium can be eluted with nitric acid solution as eluent. Therefore, the TiSbA exchanger can be used repeatedly for the separation of lithium ions from seawater and hydrothermal water.
