Abstract Scope |
Growing concerns over the lack of safe permanent disposal of nuclear waste has fueled vast research to develop innovative materials capable of capturing and immobilizing radioactive waste, such as radioactive iodine (129I). Silica-based porous sorbents offer many intrinsic qualities such as high surface area, chemical stability, ease of functionalization and transformability into a stable waste form that make them promising candidates for capturing and immobilizing 129I. Their commercial implementation is contingent on their ability to mechanically withstand gas flow conditions. This work attempts to study the in-flow mechanical behavior of metal-functionalized silica sorbents by observing and measuring the amount of mass lost by the material. Material lost is observed by a capacitance-based in-flow particle detector, and mass loss is measured by a quartz crystal microbalance. |
