Solid-state harmless conversion manner and the organicity halogen compound harmless conversion medicine which contain organicity halogen compound

摘要

PPROBLEM TO BE SOLVED: To provide a detoxification method of a solid containing an organohalogen compound, having excellent processing efficiency while an operating condition is mild and the energy consumption amount is small. PSOLUTION: The solid containing the organohalogen compound and a metal particle as an electron donor are brought into contact with each other to reduce the organohalogen compound and detoxify the same. At this time, at least some of the metal particles to be used are particles of nano size. The metal particles including particles of nano size are obtained by crushing a mixture of solid-like metal and water adsorption and desorption agent and/or a porous inorganic material until at least some of the solid-like metal becomes nano size. The obtained metal particles are dispersed in the water adsorption and desorption agent and/or a porous inorganic material to form a metal dispersed body. Thus, the high activity can be maintained.
