| Abstract;Radiovoltammetry for the ion transfer at the interface between two immiscible electrolyte solutions (RITIES) was developed. This new method is based on the measurement of the relationship between the interfacial potential of two phases and the amount of the ion transferred after controlled-potential electrolysis in stead of potential-current relationship measurement. Radioactivity of both phases was measured as the concentration of radioactive ions in the solution. RITIES has advantages, comparing with the conventional potential-current relationship measurement: (1) even at the potential where a large residual current flows, the potential-radioactivity curve can be determined; (2) ion transfer of such low concentration as tracer level can be measured. Actinide ion transfer was investigated by RITIES, and ion transfer free energy for actinide ions was estimated from these results. (author abst.) |
