    • PURPOSE: A resourcing apparatus of carbon dioxide and a method for the same are provided to prevent hydroxide ions from being converted into oxygen, and to selectively use the hydroxide ions by using a double membrane. CONSTITUTION: A resourcing apparatus of carbon dioxide includes an electrolyzing part(10), a carbonate ion conversion part(20), an electrosorption part, and a carbonate conversion part(30). The electrolyzing part includes a double membrane installed between two electrodes. In the electrolyzing part, water is electrolyzed into hydroxide ions and hydrogen ions. The carbonate ion conversion part is formed at the rear part of the electrolyzing part and converts carbon dioxide into carbonate ions. The electrosorption part absorbs metals from the water. The carbonate conversion part is connected to the carbonate ion conversion part and the electrosorption part and converts the carbonate ions into carbonate.
