Abstract

The ion exchange properties of the titanium silicate, M₂-Ti₂O₃SiO₄ ·nH₂O (M = H, Na), toward stable and radioactive ¹³⁷Cs⁺ and ⁸⁹Sr²⁺, have been examined. By studying the cesium and strontium uptake in the presence of NaNO₃, CaCl₂, NaOH, and HNO₃ (in the range of 0.01-6 M) the sodium titanium silicate was found to be an efficient Cs⁺ ion exchanger in acid, neutral, and alkaline media and an efficient Sr²⁺ ion exchanger in neutral and alkaline media, which makes it promising for treatment of contaminated environmental media and biological systems.
