Uranium(VI) Uptake by Calcium Silicate Hydrates

Batch sorption studies show strong retention of U(VI) by C-S-H phases
U(VI) retention by C-S-H phases may be controlled by the formation of a Ca-U(VI) solid-solution
TRLFS studies indicate the presence of sorbed U(VI) species in an uranate-like coordination environment at high loadings and sorbed U(VI) species in an Ca-UO2-silicate-like coordination environment at low loadings.
