Crystalline Silicotitanate: a New Type of Ion Exchanger for Cs Removal from Liquid Waste
Crystalline Silicotitanate：a New Type of Ion Exchanger for Cs Removal from Liquid Waste

The research and developments of a new type of inorganic ion exchanger, crystalline silicotitanate (CST) are reviewed. This material is stable against radiation, and the CST has high selectivity for Cs over Na, K and Rb. It performs well in acidic, neutral, and basic solutions. The results of ion exchange tests show that CST is an excellent candidate for Cs removal from high-level liquid waste.
