Abstract
The sorption behavior of aqueous Pu(IV) on brucite (Mg(OH)(2)) in the prese nce and absence of citrate was investigated by a combination of wet chemica l batch sorption experiments and X-ray photoelectron spectroscopy (XPS). So rption occurs rapidly at near 100% levels from pH 8 to pH 13, and is not af fected by the presence of citrate. XPS results indicate that Pu was incorpo rated in the subsurface in the cases studied.
