Aqueous Pu(IV) sorption on brucite

The sorption behavior of aqueous Pu(IV) on brucite (Mg(OH)₂) in the presence and absence of citrate was investigated by a combination of wet chemical batch sorption experiments and X-ray photoelectron spectroscopy (XPS). Sorption occurs rapidly at near 100% levels from pH 8 to pH 13, and is not affected by the presence of citrate. XPS results indicate that Pu was incorporated in the subsurface in the cases studied.
