Interaction of 99Tc onto bentonite and influence of Fe(II) and Ca,Mg ion exchange in its interlayers

Original language description

99Tc is redox active radionuclide, which is present as contaminant at a number of sites where nuclear fuel cycle operations have been carried out. The aim of our research was study of bentonite interaction with Fe and Fe2+ cation and these influences onthe 99TcO4- migration behavior. Radioanalytical and analytical methods were used for the concentration and chemical forms of 99Tc determination. It was found that Fe2+- Ca2+, Mg2+ ion exchange should be considered as a process of reaction among the corrosion products of carbon steel container and bentonite in the environment of radioactive waste repository.
