Ion is an important chemical form in environment, human body, energy storage, etc. We have successfully developed electrodialytic ion handling method which can quantitatively transfer ionic solutes from one to other solution phases. And we are applying this to sample pretreatment for chemical analysis, speciation analysis of chromium species, separation of radio active isotopes from target materials, in-line synthesis and separations of amino acids and chiral compounds.

Cu2+ ion is transferred into ligand solution to synthesize radioactive probe.
