ABSTRACT:
There is described a process for the recovery of deuterium and tritium from their oxides, such has heavy water and tritiated water, comprising the steps of reacting the oxides of deuterium and tritium with an intermetallic compound having a formula ZrM.sub.2, where M is a transition metal chosen from the group comprising Cr, Mn, Fe, Co and Ni such that it sorbs oxygen and released deuterium and tritium. The reaction preferably occurs by contacting the impure gas with the ZrM.sub.2 alloy as defined above, in the form of a compressed powder. A preferred alloy is the intermetallic ternary compound ZrMnFe.
