Abstract
A halogenated organic compound is introduced into a plasma. In the plasma state, substances are very reactive and chemical substances which are not readily decomposed such as halogenated organic compounds are decomposed in a short time. Specifically, in a high-temperature plasma exceeding 10,000.degree. C., almost all molecules are considered to dissociate into atoms. A reactive substance such as water is introduced into a plasma together with a halogenated organic compound. The decomposed halogenated organic compound is caused to react with the reactive substance, for preventing the decomposed organic compound from returning to its original state.
