Uranium(VI) retention in clay rocks with saline pore waters


Uranium(VI) retention in clay rocks with saline pore waters

Fritsch, K.; Schmeide, K.

Argillaceous rock is considered as one of the possible host rock types for radioactive waste repositories in Germany. Therefore, it is necessary to examine the retention behaviour of argillaceous rock towards long-lived radionuclides, such as uranium. In this study, the bentonite montmorillonite is used as a model clay. The sorption of uranium(VI) onto montmorillonite is studied in NaCl and CaCl2, in dependence on pH and ionic strength.

Keywords: uranium sorption; argillaceous rock; clay; uranium; montmorillonite; high ionic strength
