摘要： An agent for removing organic chlorine compounds which is composed of (A) an iron powder having a BET specific surface area of from 0.010 to 3 m2/g, and (B1) a powder of at least one species of metal selected from the group VIII elements (excluding Fe) in the periodic table, and/or (B2) a porous substance in powder form supporting said metal. If the agent is composed of (A) and (B1), the amount of (B1) is 0.01 to 10 parts by mass for 100 parts by mass of (A). If the agent is composed of (A) and (B2), the amount of (B2) is 0.0001 to 10 parts by mass for 100 parts by mass of (A). This agent is capable of removing organic chlorine compounds efficiently.

摘要： The invention provides an iron-based cleaning powder capable of efficiently decomposing organic halides. The iron-based cleaning powder is made of iron alloy powder or iron powder produced with an atomization process. The iron alloy powder passes a 300 &mgr;m-mesh sieve at a proportion of not less than 90% and has an H2-reduction mass loss of 0.1 to 0.8% when it contains 0.3 to 1.1% of Mn. When the iron alloy powder contains 0.2 to 12% of Ni, it has an H2-reduction mass loss of 0.1 to 1.0%. The iron powder is used as mixed powder or partially alloyed powder together with Ni-containing powder. The iron powder passes a 300 &mgr;m-mesh sieve at a proportion of not less than 90% and has an H2-reduction mass loss of 0.1 to 1.0%. The Ni-containing powder has a Ni content of not less than 40% and passes a 45 &mgr;m-mesh sieve at a proportion of not less than 90%. The iron alloy powder and the iron powder have a martensite structure or a tempered martensite structure.
