Title: ADSORPTION MATERIAL
Abstract:
The purpose of the present invention is to provide an adsorption material containing a crystalline silicotitanate which is effective for adsorption of cesium and further for adsorption of strontium even in sea water. The adsorption material of the present invention is a cesium and/or strontium adsorption material which contains crystalline silicotitanate which is represented by a general formula; A4Ti4Si3O16·nH2O (where, A represents one or two kinds of alkali metal selected from Na and K, and n represents 0 to 8), and which has a crystallite diameter of 60 nm or more and a half value width of the diffraction peak of 0.9 degree or less in a lattice plane (100 plane).
