Title: Method for lithium extraction via ion exchange

Abstract

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