Abstract:

Zeolite inorganic ion exchangers provide unique combinations of selectivity, capacity, stability and molecular sieving effect not available in other ion exchangers. Ion exchange is an efficient and widely used method for the treatment of radioactive waste liquids, as well as for the separation of radioisotopes. Zeolites and their zeotypes have been recognized as materials for the solidification and fixation of radioactive waste contaminants originating from nuclear power or reprocessing plants and other radioactive research laboratories. These exchangers possess high selectivity for certain ions or group of ions and can be utilized for the separation of such ions. In addition, they have marked superiority over commercially available cation exchange organic resins due to high cation exchange capability, thermal, radiolysis, and the possibility of transformation to stable ceramics and compatibility with cement.
