Hydrous silicon(IV)–titanium(IV) oxide ion exchanger was prepared by using TiCl<SUB>4</SUB> and Na<SUB>2</SUB>SiCO<SUB>3</SUB> solutions. From a detailed examination of the dependency of the compositions and the acid–base properties of the products on the conditions for precipitation, a reproducible synthetic procedure was established. The exchangers with 37 to 67 mol% of titanium to metallic elements possess much larger ion-exchange capacities and are more stable to highly alkaline solutions than simple mixtures of hydrous silicon(IV) oxide and hydrous titanium(IV) oxide. The dependency of the ion-exchange capacity on the composition can be explained by the difference in the structure of the matrix as evidenced from the thermal analysis, X-ray diffraction, and infrared absorption studies.
