The invention discloses a Cu (I) (at) MIL-100 (Fe) pi complexing adsorbent and a preparation method thereof, and the method comprises the following steps: firstly mixing a bivalent copper salt, a trivalent iron salt, an organic ligand and deionized water, then reacting the mixture, and finally washing, drying and grinding the reaction product to obtain the Cu (I) (at) MIL-100 (Fe) pi complexing adsorbent. Therefore, cuprous ion sites are introduced during synthesis of MIL-100 (Fe) through a one-step method, the whole preparation process is safe, simple and convenient, synthesis under harsh conditions such as a dry inert atmosphere or vacuum is not needed, and the method is environment-friendly and relatively low in energy consumption. Besides, the Cu (I) (at) MIL-100 (Fe) pi complexing adsorbent prepared by the method can greatly improve the carbon monoxide adsorption capacity of an organic metal framework material MIL-100, has high specific surface area and pore volume, can maintain good adsorption performan
