Abstract
Method for recovering oxygen from a medium containing O.sub.2 using polynitrogenated compounds that have five coordinating functions which are capable of binding a metal atom, particularly a cobalt atom. In the recovery method, oxygen is first absorbed by the metal complex and then desorbed from the complex and recovered in an appropriate vessel.
