Abstract

Because of the lack of the corresponding electrochemical data, the rad ioisotope method, a modification of the moving-boundary method for measuring transforence numbers by use of radioisotopes, was applied to determine the mobility of UO ₂²⁺ in aqueous solution in a concentration range 0.1–5.10⁻⁴M. It is an example of the investigations of the transport processes of actinides in aqueous and non-aqueous electrolyte solutions in favour of conventional analytical methods and separation processes with⁶⁰Co as indicator. In order to suppress hydrolysis the majority of measurements were made in solutions of nitric acid at constant pH 2. The results on the transference number, conductivity and mobility of the UO₂-ion constituent is transferred to the standard aqueous system by van RYSSEL-BERGHE's theory. Measurements of Th-, Np-,Pu- and Am-constituents are in progress.
