Research Abstract

The purpose of the present study is to determine the redox potential of lawrencium (Lr) by an electrochemical method available for single ions. In this study, an automated electrolytic column chromatograph apparatus which is applicable to the reduction of Lr was newly developed. In a preparatory work, a carrier-free Mo radiotracer in 0.1 M HCl was electrolytically reduced from Mo(VI) to Mo(V) for the first time. In the future, on-line reduction experiments using the apparatus are planned to be performed at JAEA tandem accelerator.
