Abstract:
1. A method of treating a chemical decontamination solution, comprising: preparing a chemical decontamination solution, in which organic acid is dissolved, for dissolving oxide film adhered to a contaminated component; dissolving the oxide film adhered to the contaminated component with the chemical decontamination solution; electrolyzing the chemical decontamination solution to decompose the organic acid dissolved in the chemical decontamination solution at an anode; and adding ozone in the chemical decontamination solution to decompose the organic acid dissolved in the chemical decontamination solution; wherein in the electrolyzing of the chemical decontamination solution, a polarity of a direct power source is changed to adjust valence states of iron ions which have been provided in the chemical decontamination solution; and wherein in the adding of ozone in the chemical decontamination solution, a polarity of a direct power source is changed to decompose organic acid dissolved in the chemical decontamination solution.
