内容記述 | Absorption of protium and deuterium by Pd, Pd-4at%Pt and Pd-8at%Pt powders under 200 mesh was measured in a dilute hydrogen concentration region at temperatures from 0 to 82℃ by recording the decline of hydrogen pressure in an experimental chamber due to hydrogen absorption. These measurements and data analyses gave the adsorption rate, desorption rate and diffusion constants of hydrogen isotopes for the alloys. The absorption was very fast, completed within a few tens of seconds, but there appeared a clear trend of decreases in the rate constants for adsorption, desorption and diffusion with increase in the Pt content in the sample. The activation energies for these rate processes increased with increase in the platinum content. Regarding isotope effects, protium showed a higher adsorption rate but lower desorption rate in the present temperature range. It was also found that protium diffused more slowly than did deuterium in all three samples. | |||||
