Zusammenfassung:Provided are a carbon dioxide fixation method and a carbon dioxide fixation apparatus, wherein seawater (7) is electrolyzed, anodic electrolyzed water (7a) and cathodic electrolyzed water (7b) that are generated from the electrolysis of seawater are separated from each other, the pH of the anodic electrolyzed water is adjusted by adding alkaline agent thereinto, carbon dioxide gas is blown into the cathodic electrolyzed water to fix the carbon dioxide gas as carbonate, and the pH-adjusted anodic electrolyzed water and the carbonate-fixed cathodic electrolyzed water are joined together and adjusted the pH thereof equivalent to a pH of seawater to discharge. In this way, the carbon dioxide fixation method and carbon dioxide fixation apparatus can be provided, which fix carbon dioxide gas with low-impact to the environment, or no concern for the re-release.
