摘要： The invention provides an industrially advantageous method for producing a crystalline silicotitanate having high adsorption/removal capabilities for cesium and strontium in seawater. The method includes a first step of mixing a silicic acid source, a sodium compound, titanium tetrachloride, and water to prepare a mixed gel and a second step of hydrothermal reaction of the mixed gel prepared in the first step to produce crystalline silicotitanate of formula: Na4Ti4Si3O16.nH2O (wherein n represents 0 to 8). In the first step, the silicic acid source, sodium compound, and titanium tetrachloride are mixed in such a mixing ratio that the resulting mixed gel may have a Ti to Si molar ratio, Ti/Si, of 1.2 to 1.5 and an Na2O to SiO2 molar ratio, Na2O/SiO2, of 0.7 to 2.5.
