| Outline of Final Research Achievements |
Development of chemical isotope separation towards multistage process:1 Dramatic improvements of distribution coefficient and separation factor were obtained for one order and 2 times, respectively by adding 12M HCl in Ca aqueous solution (30% 3.5M).2 We obtained a similar value of 15% distribution coefficient with the batch liquid-liquid extraction process and its Ca transfer between two phases without any stirring for only 0.3 sec (6000 times faster than batch process with magnetic stirrer for 30 min) on a chip.3 Development of quick and easy (without preprocessing) method for isotope ratio measurement by ICP-MS: We succeeded an accurate measurement of isotope ratio by changing from hot plasma with reaction-cell to cool plasma with reducing interference from Ar gas. Our method utilizes a high Ca concentration of 100/400 times for crown-ether resin and electrophoresis, respectively and its crown-ether can be recycled. These enables us to achieve a cost-effective mass production.
