摘要
Continuous flow-through column experiments have been performed to determine the sorption of uranium in granite-hematite mixtures. The results obtained have shown the importance that oxy-hydroxy iron compounds present as fracture fillings can have in the uranium retardation in its migration through the geosphere. The experimental results showed the reversibility of the sorption process and have been successfully fitted with a model combining both thermodynamic and kinetic terms.
