Outline of Final Research Achievements

In the present study, an on-line solvent extraction apparatus and a liquid scintillation counting system based on flow injection analysis was newly developed to study chemical properties such as redox potentials and complex formation of superheavy element, element 113 (E113). Combining the developed solvent extraction apparatus with an on-line dissolution unit which had been already developed, extraction experiments of a short-lived molybdenum isotope was successfully carried out. Oxidation experiments of manganese were also performed using a flow electrolytic apparatus. Results showed that a tracer amount of manganese is specifically adsorbed on the electrode, which would be possibly used to determine the oxidation potential of E113.
