Cm(III) Sorption onto Sapphire (α-Al2O3) Single Crystals. — Cm(III) sorption
onto different crystal planes of sapphire single crystals is characterized at low Cm(III)
concentrations and pH 4.5 and 5.1 by time-resolved laser fluorescence spectroscopy,
XPS, α-spectrometry, and autoradiography. The methods are sufficiently sensitive to
characterize surface sorbed Cm(III) species even at low surface coverage. The extent
of Cm(III) sorption differs for the individual crystal planes, with the highest sorption
taking place at the (001) orientation and the lowest at the (018) orientation. By combination of different experimental methods, a better understanding of the reactions on the
water/single crystal surface interface is achieved. Oxide surfaces experiencing extensive surface hydroxylation and surface phase transformations may control the sorption
of metal ions in natural systems. — (RABUNG*, T.; SCHILD, D.; GECKEIS, H.;
