Document Type and Number:
WIPO Patent Application WO/2012/039334
Kind Code:
A1
Abstract:
Provided are: a decomposition agent which needs not to contain copper, is composed of iron particles, and is capable of decomposing an organic halogen compound satisfactorily; and a process for producing the decomposition agent. The decomposition agent for an organic halogen compound comprises iron particles composed of iron and iron oxide, wherein the outermost surface layer of each of the iron particles has a metal iron content of 15 mass% or more when two rounds of ion beam etching are carried out under the following etching conditions: the degree of vacuum in a chamber: 2.0×10-2 Pa; the accelerating voltage of an ion gun: 10 kV; the emission current: 10 mA; and the etching time: 14 seconds.
