| Abstract;In the last two years, we have developed a gas-jet coupled target system for production of the transactinide elements and an automated chemical processing system for fast and repetitive high performance liquid chromatography separation in order to investigate the chemical properties of the transactinide elements. We first intend to produce element 104, rutherfordium (261Rf), and to perform its chemical experiment in aqueous systems. It is also important to compare the chemical properties of Rf with those of its lighter group 4 homologues Zr and Hf and its tetravalent actinide pseudo-homologue Th in order to verify influences of the relativistic effect. For this purpose, radiotracers of 88Zr, 175Hf, and 234Th were prepared and various chemical properties such as absorption behavior and ion exchange behavior are now under study. (author abst.) |
