THE DEPENDENCE OF THE ELECTROLYTIC HYDROGEN-DEUTERIUM SEPARATION FACTOR ON THE ELECTRODE POTENTIAL
The influence of the electrode potential on the cathodic hydrogen- deuterium separation factor was determined with potentiostatic experiments. Additional variables studied were electrode materials, temperature, and surface roughness (porous vs. smooth electrodes). The separation factor S was found to pass through a maximum as increasingly negative electrode potentials were applied. The maximum for S occurred at a different potential for each electrode material. In the decreasing region at high negative potentials, the influence of the individual electrode material on S decreased, and the data for all electrodes merged and could be represented by a single line with a scatter of only 25%. The porous electrodes gave separation factors 10 to 100% smaller than the smooth electrodes. The separation factor decreased with increasing temperature by about 1% per deg C in the range 30 to 50 deg . (auth)
