| Popis: | The separation of 12C and 13C isotopes by acid-base chromatography using an anion-exchange resin was investigated. In order to design the separation system, equilibria with respect to a carbon band were examined with reduction potential strength. Simulation and analysis with the potential strength and the newly derived S and L potentials were found useful for determining experimental conditions. Isotopic separation factors between CO2 and HCO3 observed in the chromatographic experiments were nearly equal to those in the corresponding solutions. The experiments at 25 or 90[ddot]C gave values of about 1.25 to 1.26 × 10−2 as the isotropic molar ratio of 13C at the rear boundary of the carbon band. |
