Abstract
Methods for extracting lithium from solutions containing lithium ions via reversible cation exchange with Hare provided. The methods utilize metal oxide or metalloid oxide cation exchange materials having an active sublattice that preferentially bind Lications, relative to both Hand Na, in a sample solution and preferentially bind H, relative to Li, in an acidic solution.
