测定了氚在高浓度氚化水中生产纯氚气的钯银阴极膜中的扩散和吸附参数值及其同位素。结果表明，渗透率随外加阴极电位、温度和阴极入口表面钯黑沉积的存在而增加。扩散系数、合金中的氚浓度和扩散层厚度与温度有关。钯银膜上钯黑沉积的存在改善了对氚的吸附。
The diffusion and adsorption parameter values of tritium in palladium-silver cathodic membranes used to produce pure tritium gas and its isotopes from highly concentrated tritiated water are determined. It is shown that permeation increases with applied cathodic potential, temperature, and the presence of a palladium black deposit on the cathodic entry surface. The diffusion coefficient, tritium concentration in the alloy, and the diffusion layer thickness depend on temperature. The presence ofa palladium black deposit on the palladium-silver membrane improves the adsorption of tritium.
