Sorption Values for Niobium and Tin,) hydrolyse extensively and exist under cementitious conditions as negatively charged hydroxo-complexes. Tin and niobium are contained in various wastes from nuclear power production. Both elements sorb strongly on cementitious materials under all conditions, in accordance with their hydrolysis beha

Sorption Values for Zirconium,corrosion. In aqueous solutions, zirconium exists exclusively in the tetravalent oxidation state. Zr(IV) hydrolyses strongly with Zr(OH).(aq), and Zr(OH)... being the only relevant species in cementitious environments (and low zirconium concentration). Very high sorption of zirconium has been observ

Sorption Values for Americium,. Spectroscopic information suggests that sorption occurs through surface adsorption as well as through incorporation into the CSH structure, replacing Ca. Similarly, incorporation into the calcite lattice is supported by spectroscopic evidence.

Sorption Values for Palladium and Lead,on) and especially pH or C/S ratio, where a decrease leads to an increase of lead sorption. Kinetic data for Pb sorption indicate a fast initial (chemical) sorption step, followed by a much slower process, possibly involving diffusion into the solid matrix.

Sorption Values for Niobium and Tin,ed cement paste differs between the two solids, but corresponds to the formation of inner-sphere complexes in both cases. However, it has to be admitted that the available information is not conclusive with regard to (i) identifying the sorption-dominating mineral phase and (ii) the distinction between surface sorption or/and incorporation.

Sorption Values for Zirconium,radation, in particular from a C/S ratio of 1.3 to 1.0. While the actual sorption mechanisms for zirconium are not known, the available evidence suggests that mainly CSH phases are responsible for zirconium sorption on cementitious materials.
