Abstract
Abstract A method of recovering deuterium and tritium from hydrogen comprising exposing vanadium hydride to gaseous mixtures containing the heavy isotopes of hydrogen and allowing the heavy isotopes to undergo mass transference with the hydrogen of the vanadium hydride until the ratio of heavy hydrogen isotope atoms to hydrogen atoms in the vanadium hydride is greater than the ratio in the gas.

The process of enriching a solid whose composition lies within the range V-VH2 with at least one heavy hydrogen isotope comprising the step of exposing said solid to a gas containing hydrogen and at least one of its heavy isotopes at a temperature in the range of -50*C to 110*C and a pressure above the dissociation pressure of the hydrided V until the ratio of the heavy hydrogen isotope to the light isotope in the hydrided V is greater than the same ratio in the contacting gas, thereafter removing said gas leaving the solid enriched with said heavy hydrogen isotope.
