PURPOSE:To obtain the titled adsorbent free from the deterioration of performance even if repeating adsorption and desorption by using a resin having pyridyl group, cuprous halide and/or cuprous chiocyanate as constitutional components. CONSTITUTION:Cuprous halide and/or cuprous chiocyanate and a solvent (i.e. acetonitrile or the like) are mixed and stirred. Then dried resin having pyridyl group is added thereto and stirred and the mixture is heated under reduced pressure to sufficiently distill the solvent, and an adsorbent being a solid for carbon monoxide is obtained. As the composition of this adsorbent, in case of using either one hand of cuprous halide and cuprous thiocyanate as the constitutional component, the ratio of the molar number of pyridyl group incorporated in resin to the molar number of copper salt is 0.1-30 preferably 0.5-3. Further in case of using both cuprous halide and cuprous thiocyanate as the constitutional components, the ratio of the molar number of pyridyl group incorporated in resin to the sum of the molar number of both copper salts is 0.1-30 preferably 0.5-3. |
