Abstract: An object is to provide a cage silicate that can be industrially safely and simply produced by using an alkali silicate solution that does not generate alcohol as a Si raw material and using non-toxic quaternary ammonium, and a method for producing the same. The problem is solved by the following cage silicate:



A cage silicate consisting of anion component 1 represented by following formula (1), anion component 2 which is a mineral acid ion, cation component 1 represented by following formula (2), and cation component 2 which is an alkali ion, in which, to the mole number in terms of SiO2, a ratio of the mole number of water, (H2O/SiO2), is 0.7 to 30, a ratio of the mole number of alkali ions, (alkali ions/SiO2), is 1.0×10−7 to 1.0×10−2, and a ratio of the mole number of the mineral acid ions, (mineral acid ions/SiO2), is 1.0×10−7 to 1.0×10−3.








In formula (2), R represents an alkyl group having 2 to 20 carbon atoms.

Abstract: The present invention provides a method for purifying a liquid to be treated, the method being capable of reducing the content of metal impurities in the liquid to be treated containing tetraalkylammonium ions, and further, being capable of suppressing cracking of the resin even when a strongly acidic cation exchange resin is used. The method includes: an impurity removal step of passing a liquid to be treated that contains tetraalkylammonium ions and metal impurities through a container filled with a cation exchange resin of a hydrogen ion form or a tetraalkylammonium ion form to reduce the content of the metal impurities in the liquid to be treated, wherein the degree of cross-linking of the cation exchange resin is from 16% to 24%.
