Abstract

Clinoptilolite, a common natural zeolite was chemically modified with HCl and Si to enable the sequestration of Cs and Sr isotopes, in both water and some types of solid waste (nuclear industry residues, for instance). The method reported allows to preserve the crystalline structure of the zeolite, thus maintaining its advantageous textural characteristics, while incorporating the adequate surfacemoieties for various applications, including trapping of polluting ions in water.
