Adsorption of actinides on cement compounds
The sorption of thorium, uranium, neptunium, plutonium and americium on hydrotalcite, tobermorite, ettringite and calcium silicate hydrate gel were investigated in water, saturated NaCl solution and Q-brine at 25, 55 and 85 degrees C. Speciation was also studied. The data obtained will fulfill Freundlich's isotherm if the ion constituent is taken as a parameter but even Langmuir's isotherm will be valid if the ionic concentration of the various ionic species is be taken into account. A theoretical parameter was found which permits the solution capability of the various cementitious materials to be compared with respect to the relevant ionic species present.
