 note = {application/pdf, Electroless Pd plating on Zr3Al2 granules was prepared as a protective layer on the getter alloy surface. The absorption of deuterium obeyed the first order kinetics with respect to the deuterium pressure for both Zr3Al2 and Pd/ Zr3Al2. The rate determining step for absorption was the dissociation reaction of gaseous and/or adsorbed deuterium molecules on the surface. The activation energy was evaluated to be 7.4 and 8.9 kJ/mol (D2) for Zr3Al2 and Pd/ Zr3Al2, respectively. In addition, the durability against impurity gases for deuterium absorption was also demonstrated using CO2 and N2 as impurity gases. Exposure to these impurity gases caused a reduction of the absorption rate of deuterium. The extent of the reduction for Pd/Zr3Al2 was smaller than that for bare Zr3Al2. The effectiveness of the Pd-overlayer against impurity gases was in the order of N2>CO2. The results could be explained in terms of different absorption propertyes of deuterium between Pd and Zr., Article},
