• Active carbon-supported aluminium copper(I) chloride (AlCuCl<SUB>4</SUB>) is prepared by mixing active carbon with toluene solution of AlCuCl<SUB>4</SUB>, followed by the removal of the liquid phase at 6 mmHg, 100 °C. The active carbon-supported AlCuCl<SUB>4</SUB> rapidly adsorbs carbon monoxide (CO) at 20 °C under 1 atm from 9:1 CO–N<SUB>2</SUB> mixture and the equilibrium molar ratio of adsorbed CO to AlCuCl<SUB>4</SUB> is 1.03. Adsorbed CO is desorbed either by reducing pressure or by elevating temperature. In the second adsorption, which is carried out after the desorption at 6 mmHg, 20 °C for 10 min, the molar ratio of adsorbed CO to AlCuCl<SUB>4</SUB> is 0.51. The molar ratios are constant at 0.51 in the third and later adsorptions. The CO adsorbing ability of the active carbon-supported AlCuCl<SUB>4</SUB> remains virtually unchanged on repeated contacts with nitrogen gas containing 9000 ppm of water.
