Abstract
A carbon dioxide fixation method includes: immersing a magnesium alloy in an aqueous solvent; blowing carbon dioxide-containing gas into the aqueous solvent; and electrically energizing and thereby subjecting the aqueous solvent to electrolysis treatment so as to produce precipitates containing magnesium carbonate. The method can be carried out in a system having: a treating bath for storing a magnesium alloy and an aqueous solvent to treat a magnesium alloy in which the magnesium alloy is treated, a gas-introducing unit for blowing carbon dioxide-containing gas into the aqueous solvent, a pair of electrodes for applying voltage to the aqueous solvent so as to conduct electrolysis treatment, and a power control unit connected to the electrodes.
