Abstract
Antimonates of Sn (IV) and Ti (IV),λ- and cryptomelane type-MnO2, hydrotalcite, hydrous oxides of Ti (IV) and Zr (IV), crystalline antimonic (V) acid (Sb2O5·4H2O), and α-Zr (HPO4)2 were studied for selective uptake of lithium from seawater by the batch and column methods and the extraction features were compared. Among these inorganic ion exchangers studied, metal antimonates exhibited the most effective uptake of Li+ from seawater.
