PROBLEM TO BE SOLVED: To provide a method of wet oxidation treatment that improves oxidation efficiency, keeps down the cost, and gives simple processing after the oxidation treatment.SOLUTION: Oxidation objects having hydrophobicity before oxidation treatment and hydrophilicity after the oxidation treatment, for example nanocarbons such as a carbon nanotube, are brought into contact with an ozone solution and subjected to the oxidation treatment with ozone dissolved in the ozone solution. An ozone solution prepared by dissolving ozone in a two-phase solvent of water and a fluorine-based solvent is used in the above oxidation treatment. |
