【 摘 要 】

The present study discusses the effect of gamma-irradiation on Cs(+)-exchanged X and A zeolites. The incorporation of Cs(+) ions into A and X zeolites was performed using three different cesium salts (chloride, nitrate or acetate). Cs(+) ions immobilized into the vitrified zeolites by thermal treatment are located in different sites of the zeolite networks. It is found that gamma-irradiation favors cesium retention depending on the cesium precursor salt used in the cationic exchange step. (C) 2008 Elsevier B.V. All rights reserved.
