The invention discloses a method for improving carbon monoxide absorption and separation capacity by using halogen bond action. An ionic liquid composite system composed of cations containing halogen structures, anions containing cuprous structures and alcohol compounds is used as an absorbent and used for absorbing carbon monoxide, and in the absorption process, the gas absorption pressure is 10 kPa to 500 kPa, the absorption temperature is 20 DEG C to 80 DEG C, and the absorption time is 1 h to 5 h; in the desorption process of the ionic liquid composite system absorbing saturated carbon monoxide, the composite absorbent system after absorption in the absorption tank is directly vacuumized, the desorption temperature is 80-100 DEG C, and the desorption time is 0.5-1 h. Through the design of an ionic liquid composite system, the interaction between anions and cations is regulated, and the reaction between cuprous sites and carbon monoxide is regulated by utilizing the halogen bond action ...
