▎ 摘　　要

NOVELTY - Carbon monoxide adsorbent comprises a carrier and an active component loaded on the carrier. The carrier is a porous carbon material, and the active component is copper (I) and manganese (II). USE - Used as carbon monoxide adsorbent. ADVANTAGE - The adsorbent has high CO adsorption capacity, and mild conditions. The method is simple, and has good industrial application prospects. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: Preparing the adsorbent, comprising (i) providing an active component solution containing copper salt and manganese salt, (ii) impregnating the porous carbon material with the active component solution, and roasting under an inert atmosphere, where the copper salt is copper chloride, and the manganese salt is divalent manganese salt. Carbon monoxide adsorption method, comprising contacting a gas containing carbon monoxide with an adsorbent to adsorb carbon monoxide contained in the gas on the adsorbent, where the adsorbent is the carbon monoxide adsorbent or the carbon monoxide adsorbent.
