Abstract: A process for the recovery of deuterium from a gas having deuterium values and oxygen bearing impurities by contacting the gas with a solution of sodium or lithium in ammonia to eliminate oxygen-bearing impurities as sparingly soluble reaction products. The NH3-Na or Li solution contacts the synthesis gas saturated with NH3 having oxygen impurities and deuterium values therein and the deuterium rich ammonia gases from a deuterium enrichment unit in order to achieve saturation of higher deuterium concentration. The ammonia gases saturated with deuterium values are finally passed on to the deuterium enrichment unit to recover deuterium values and to produce ammonia depleted of deuterium. The preparation and/or stock tank for the Na -or Li- solution in NH3 is provided with a lining material selected from the group consisting of copper, non-ferrous metal and plastics because the NH3-Na solution resides in these containers for an extended period of time.
