Ion-exchange properties of zeolite/glass hybrid materials

Abstract

Hybrid materials were prepared from ground glass powder and various zeolites such as A-type, mordenite, X-type, and Y-type zeolites, and their ion removal effect was investigated. The hybrid materials of A-type, Y-type, and mordenite zeolites showed similar Sr2+ removal rates from aqueous solutions. The removal rate of Sr2+ ions increased as the amount of zeolite in the hybrid materials increased. Compared with other hybrid materials, the hybrid materials of X-type zeolite showed higher Sr2+ removal rates, especially for zeolite content greater than 25%. As the amount of X-type zeolite in the hybrid materials increased, the Sr2+ removal rate increased greatly, with a 100% removal rate when the content of X-type zeolite exceeded 62.5%.
