Abstract:
1. A method of manufacturing a perchlorate, comprising: an electrolysis process in which, using an electrolysis tank in which an anode section provided with an anode and a cathode section provided with a cathode are divided by a cation-exchange membrane, an aqueous solution of sodium chlorate is electrolytically oxidized in the anode section; and a neutralization reaction process in which a substance that becomes alkaline when dissolved in water is added to the aqueous solution of perchloric acid in the anode section, which has been generated by the electrolytic oxidation, so as to synthesize a perchlorate with a neutralization reaction, wherein the anode is an electrode having a platinum catalytic layer on the surface of the substrate, and an absorption process in which at least a part of the platinum that is eluted by the electrolysis process is absorbed and recovered by an absorbent is provided between the electrolysis process and the neutralization process.
