The present invention relates to a carbon monoxide separation membrane including a hemoglobin-containing liquid film, and a method for separating carbon monoxide from carbon monoxide-containing gas by using same and, more particularly, to a carbon monoxide separation membrane including a porous support; and a hemoglobin-containing liquid film that is formed on the porous support or is filled in pores of the porous support, and a method for separating carbon monoxide from carbon monoxide-containing gas by using same. According to the carbon monoxide separation membrane of the present invention, carbon monoxide can be effectively separated from the carbon monoxide-containing gas by using a selective reaction between hemoglobin and the carbon monoxide, pre-treatment conditions are simpler than in an adsorption method, an absorption method, and a cryogenic method of the related art, and selective carbon monoxide separation is available even in a state where moisture is present. The present invention can be applied in quantity when modulized and has high economic advantages.
