This invention provides an ultramicroporous porous coordination polymer, its preparation method, and its application in the adsorption and separation of carbon dioxide, relating to the field of novel materials for gas-phase adsorption and separation. The material is named TCE-NH2ipa, with the chemical formula [Co2(bpt)2(NH2ipa)2]. n In this method, Co represents the metal center cobalt, bpt represents the organic ligand 4-(3-pyridin-4-yl-1H-1,2,4-triazol-5-yl)pyridine, and NH2ipa represents the organic ligand 3-aminoisophthalic acid. The method involves fully dissolving bpt, NH2ipa, and Co(NO3)2·6H2O, transferring the solution to a pressure-resistant sealed container, and heating it for reaction. After the reaction is complete, solvent exchange and heating activation steps are performed to finally obtain a homogeneous powdered material. The TCE-NH2ipa material of this invention exhibits good adsorption capacity for carbon dioxide, hardly adsorbs nitrogen at room temperature and pressure, and can selectively adsorb carbon dioxide in an acetylene / carbon dioxide mixture, demonstrating excellent selectivity and scalability.

In the present invention, a porous coordination polymer in which metal ions are coordinated with organic ligands is brought into contact with an ammonia-containing liquid or ammonia-containing gas, the porous coordination polymer adsorbs ammonia, and then the ammonia-adsorbed porous coordination polymer releases ammonia, and the ammonia is recovered. The porous coordination polymer that is brought into contact with the ammonia-containing liquid preferably has a water-soluble organic solvent attached thereto. The ammonia-containing gas is preferably adjusted so as to contain 106 mass parts or more of water per 100 mass parts of ammonia.
