Analysis of radioactive elements in waters of high pH
What is it about?
High pH environments are expected to evolve within and around a radioactive waste repository, where there will be extensive use of concrete as part of the design. To inform the safety case with experimental evidence, tools need to be developed and tested to enable experiments to be performed under such conditions. The diffusive gradients in thin-flms water analysis technique can yield time averaged dissolved concentrations, but to date, its suitability for high pH environments has not been tested. Here we show that the Chelex binding gel is suitable for europium for circumneutral pH, for uranyl up to at least pH 10.7 and for neptunyl up to at least pH 11.7.
