Recent progresses in the methods of the separation of carbon monoxide from gas mixtures and those in the methods of purification of carbon monoxide are reviewed. Almost all of the methods take advantage of liquid absorbents or solid adsorbents, which absorb or adsorb carbon monoxide at ambient temperature, 1 atm (or higher), and release carbon monoxide at elevated temperatures or at reduced pressures. Important progresses are divided mainly into two categories : <BR>1) preparations of liquid absorbents, which show highly selective separations and purifications under mild conditions, and in addition are stable against reactive components in gas mixtures such as hydrogen sulfide and water, and 2) preparations of solid adsorbents, which separate and purify carbon monoxide without contamination of any solvent vapors and furthermore are easily applicable to practical purposes.<BR>Advantages and disadvantages of these absorbents or adsorbents As well as their preparations are described.
