METHOD OF PRODUCING IRON POWDER FOR TREATING HALOGENATED ORGANIC COMPOUND AND METHOD OF CLEANING CONTAMINATED SOIL OR GROUNDWATER |
摘要 |
There is provided iron powder having a halogenated organic compound treating performance equivalent to or higher than that of a material for treating halogenated organic compounds, although an environmental load substance such as copper is not contained, and a method of producing iron powder for treating halogenated organic compounds including: immersing the iron powder in one or more kinds of solvents selected from water and organic solvents which have lower vapor pressure than water and contain oxygen; performing solid-liquid separation for the iron powder immersed in the solvent, to thereby obtain the iron powder wet by this solvent; and applying drying treatment to the iron powder wet in the solvent, while keeping a temperature at less than 40° C. |
