| Popis: | Gamma spectroscopy was used to quantify the accumulation of the uranyl ion (UO22+) into mesoporous silica gel in an aqueous solution under static and pressure-driven flow conditions. The amount of uranyl accumulated into silica gel under static conditions does not trend with the surface area reported by the manufacturer, but it is controlled by the silica gel permeability. Under flow conditions, the amount of uranyl deposited within mesoporous silica gel increases with pore size and ion removal efficiencies ranging from 1.8 to 7.0% were observed. Uranium transport and accumulation within mesoporous silicates is important in environmental monitoring, waste management and remediation. |
