Development of Separation Materials Containing Palladium for Hydrogen Isotopes Separation

Displacement chromatography(DC) is a ascendant technique for hydrogen isotopes separation. The performance of separation materials is a key factor to determine the separation effect of DC. At present, kinds of materials are researched, including palladium materials and non-palladium materials. It is hardly replaceable because of its excellent separation performance, although palladium is expensive. The theory of hydrogen isotopes separation using DC was introduced at a brief manner, while several palladium separation materials were expatiated in detail (Pd/K，Pd-Al₂O₃，Pd-Pt alloy). Development direction of separation materials for DC was forecasted elementarily.
