Palladium and LaNi4.7Al0.3 were proved to be promising materials for hydrogen isotope separation from experimental results of the isotope separation factor, the isotope exchange rate constant and the height equivalent to a theoretical plate(HETP). Although the displacement chromatography using a single column packed with Pd particles is an efficient separation method, it could not separate hydrogen isotopes continuously. The twin-column periodically counter-current flowing method developed here was proved to serve a continuous, efficient method for the separation of hydrogen isotope mixtures, experimentally as well as numerically.
