Application of Palladium in Hydrogen Isotopes Separation and Purification

Palladium-hydrogen system has the largest isotope effect in the metal-hydrogen systems so far as we know, so palladium is widely used in hydrogen isotopes disposal technology. The isotope effect of palladiumhydrogen system is summarized. The main applications and the development of palladium or palladium alloys in hydrogen isotopes separation and purification are reviewed.
