DECOMPOSITION METHOD OF HALOGENATED ORGANIC COMPOUND

摘要

PROBLEM TO BE SOLVED: To solve problems that a conventional radiolysis method produces alkaline waste liquid after irradiation and requires a secondary treatment such as neutralization and that the absorbed dose necessary for the decomposition is very high, 1,000 kGy or more, and its treatment cost is too high for the practical application. SOLUTION: This decomposition method treats the halogenated organic compound by adding organic solvent and/or water to a water-free treatment object solution containing halogenated organic compound or adding organic solvent to a water-containing treatment object solution containing the halogenated organic compound and irradiating radiation to promote the decomposition of the halogenated organic compound in the solution. The organic solvent has a dielectric constant higher than that of the solvent contained in the treatment object solution. COPYRIGHT: (C)2007,JPO&INPIT
