Method for dispersing nano iron particles

The invention discloses a method for dispersing nanometer iron particles. The method comprises the following steps of: (1) preparing 1-5 g/L nanometer iron aqueous solution from superfine flaky nanometer iron powder with particle size of 10-200 nm; (2) adding activated carbon with particle size less than 10 mum after hydrophilization modification with iron/carbon weight ratio of (2:1)-(1:3); (3) dispersing for 0.5-4 hours with a high-efficiency mill, and collecting liquid phase to obtain nanometer iron/activated carbon aqueous solution with stable dispersibility. The inventive method prepares nanometer iron powder with low-cost mechanical grinding; has the advantages of stable dispersibility, and no agglomeration and precipitation in several days; and can be used in ground water permeable barriers.
