From the catalystic dechlorination rates of trichloroethylene with four types of iron particle determined by the static method, it was confirmed that the reaction rates of these particles can be expressed as a pseudo-first-order reaction and that α-Fe · Fe<sub>3</sub>O<sub>4</sub> composite nanoparticles showed the highest reaction rate. As determined by static method, the "specific" reaction rate constants of iron nano- and microparticles tended to remain at certain values. Whereas they tended to decrease when the load of the particles increased. The reaction rate and "specific" reaction rate constants of iron nano- and microparticles decreased when the initial TCE concentration was high increased. The reaction rate constants of iron nanoparticles decreased markedly at a low pH and they increased at a high pH. However, the reaction rate constants of iron microparticles hardly depended on pH.
