Desorption behavior of tritiated water from organic functionalized mesoporous silica

Current advances in the utility of functionalized SBA mesoporous silica for developing encapsulated nanocatalysts: state of the art

“…Mesoporous silica materials [14][15][16][17][18][19][20] have not only proved their utilities as heterogeneous catalysts [21][22][23][24][25][26][27][28][29] for promoting various organic transformations, [30][31][32][33][34][35][36][37] but also nd interesting applications 38,39 in other research elds such as food chemistry, 40 production of bio-mass derived chemicals, [41][42][43][44][45] petrochemisry, 46-48 sensors, waste treatment, 49,50 optical materials and carriers. One of the most important advances in this eld is developing hybrid systems through functionalization of mesoporous silica materials.…”

Radioactive Wastes

“…Desorption and enrichment of tritiated water from organic functionalized mesoporous has been investigated by Taguchi et al, (2016). Results of this investigation showed that desorbed water was lower in concentration of tritiatixum measured than that in the aqueous solution used for impregnation.…”

Hydrogen Isotope (H2 and D2) Sorption Study of CHA-Type Zeolites

“…Zeolites and related porous materials have long been studied as adsorbents or desiccants [3,4] because their high surface areas and porous structures (having narrow pore diameter distributions) result in large sorption capacities and/or selective sorption properties. Among the zeolites, FAU (so-called Y or X zeolite) [5,6], MOR (mordenite) [7], LTA (3A, 4A and 5A) [8][9][10] and CHA (chabazite) [11], having pore sizes of 0.74×0.74, 0.70×0.65, 0.41×0.41 and 0.38×0.38 nm [12], respectively, have been studied as candidate materials for isotope separation, and the separation performance and sorption kinetics have been reported.…”
