The rare earth elements present strong chemical analogies with trivalent actinides, and may be used to develop methodologies and to quantify relevant processes. Nevertheless, their sorption behavior is poorly known. In this work, the authors study the sorption of ytterbium on kaolinite using surface complexation models. The aim is as a first step, to determine surface parameters of two single oxides, alumina and silica, by means of an experimental method tested on iron oxides, and in a second step to use these parameters to describe surface reactions on kaolinite surface. this application of single oxide surface parameters to aluminosilicates has been already tested and they extend this approach to study the ytterbium sorption.
