A method for purifying crude argon is disclosed. Trace amounts of oxygen and/or nitrogen are removable by using a combination of a nitride forming metal, such as lithium, and an oxygen ion conducting electrolyte cell (30, 31). Lithium may be electrolytically regenerated from the lithium nitride produced. Alternatively, a reactive metal such as lithium may be utilized to remove trace amounts of both nitrogen and oxygen from crude argon.
