The present invention relates to an adsorbent for separating carbon monoxide from a gas mixture including hydrogen gas and a method of preparing the same. The adsorbent for selectively separating monoxide includes a solid material, which is a solid support impregnated and dispersed with a cuprous salt by bringing the solid support into contact with a cuprous salt solution stabilized by dissolving a cuprous salt or a cuprous salt mixture in a solvent. The adsorbent is advantageous in that the selectivity for carbon monoxide is improved, so that the amount of carbon monoxide included in the gas mixture is decreased to infinitesimal quantities, thereby producing high-purity hydrogen products.
