Sorption von Ln(III)/An(III) und U(VI) an Tonmineralen und natürlichen Tongesteinen

In this thesis sorption of An(III)/(VI) is studied onto monomineralic clays and natural claystones by batch and spectroscopic studies and model calculations, in order to identify the minerals relevant for sorption as well as the fundamental sorption mechanisms. Furthermore, the application of sorption data determined for pure mineral phases to natural systems is discussed. The An(III)/clay outer-sphere sorption is quantified by TRLFS; the sorption site is localized by EXAFS for the first time.
