Abstract: The present invention relates to an ion sieve material, comprising, based on the weight of the ion sieve material, 15-55% by weight (wt %) of SiO2, 5-50 wt % of an auxiliary material, and 15-48 wt % of at least one functional metal oxide, wherein the metal in the functional metal oxide is a monovalent and/or divalent metal. A method for preparing the ion sieve material and a method of using the same are further provided.
