Abstract

The application of thermodynamic models to calculate Kd values for Sr/Ra and Pb on bentonite is demonstrated. The model discussed here can be used to identify relevant sorption processes, as well as other factors that determine Kd values, such as impurities contained in bentonite or artifacts (precipitation); i.e. it can be used to conduct sensitivity analyses of Kd values. Kd values can be modeled over a very wide range, indicating that such models may also be used for an evaluation of experimental data, and for predictive purposes where no such data are available.
