Abstract:
This invention relates to a method of fixing carbon dioxide by condensation polymerization in an acidic aqueous medium, thereby increasing fixation efficiency and remarkably reducing the volume of generated material compared to conventional carbon dioxide fixation methods; a polymer material prepared by the method; and a method of recovering carbon therefrom. According to the current invention, the method of fixing carbon dioxide is characterized by introducing carbon dioxide pressurized to a pressure higher than atmospheric pressure into a reactor containing a acidic aqueous medium, so that carbonic acid resulting from dissolving carbon dioxide is made into a polymer material by condensation polymerization, thereby fixing carbon dioxide, and heating the polymer material so as to recover carbon.
