Abstract: Molecular imprinting technique has good performance in predetermination, specific recognition and practicability. As molecularly imprinted polymers have advantages in predetermined molecular recognition, unique physical and chemical stability, simple preparation and reusability, the preparation of functional materials for separation has become an important development trend. Therefore, for the purpose of preparing imprinted carbon dioxide adsorbents based on the surface of attapulgite clay, this study investigated the influence of different templates, solvents, monomers and coupling agents on the attapulgite-based imprinted adsorbents. The experimental results showed that the best adsorption performance for carbon dioxide was achieved when taking oxalic acid, acetonitrile, acrylamide and EGDMA as the template, the solvent, the monomer and the coupling agent respectively. And the maximum adsorption capacity for carbon dioxide was 4.8945mmol/g.
