Sodium nonatitanate is a layered material that contains exchangeable sodium ions between layers. Zeolite A is an aluminosilicate structure that also contains exchangeable sodium ions inside the silica and alumina tetrahedral “cages”. Both of these inorganic materials are known to selectively trap divalent metals. This paper describes the preparation/characterization of these inorganic samples and...
Sodium titanate materials are promising inorganic ion exchangers for the adsorption of strontium from aqueous solutions. Sodium nonatitanate exhibits a layered structure consisting of titanate layers and exchangeable sodium ions between the layers. The materials used in this study include samples synthesized by a hydrothermal method at temperatures between 60 °C and 200 °C. Their structure, composition,...
