In a process for the separation of oxygen from a gas stream by adsorption, the improvement comprising using, as the adsorbent, a compound have the formula Mx[M'(CN)6]y wherein M is an element having an atomic number of 21, 25 to 30, 39, 50, or 57 to 59; M' is an element having an atomic number from 24 to 27; and x and y are positive whole numbers such that the sum of the valence of M times x plus the valence of [M'(CN6)] times y is equal to zero. |
