摘要：

The enrichment of tritiated water in desorption from micro- and meso-porous materials was studied. Among the adsorbents MCM-41, SEA-15, LTA(5A), and amorphous SiO2, MCM-41 showed the best enrichment ability. The tritium (T) desorption profile of MCM-41, along with Si-29 magic-angle spinning nuclear magnetic resonance spectroscopy, thermogravimetric analysis, and Fourier-transform infrared spectroscopy suggested that dehydration via the condensation of silanol groups containing T species, such as Si-OT, contributed to the enrichment of tritiated water. In contrast, the desorption of HTO molecules trapped in zeolite cages and channels was dominant in LTA(5A). The results also suggested the superiority of mesoporous structures for the enrichment of tritiated water. Crown Copyright (C) 2013 Published by Elsevier Inc. All rights reserved.
