<p>A method for removing heavy metals in a water body, characterized in that the surface of zero-valent iron is oxidized and activated using the common oxidizing agents in water treatment such as hydrogen peroxide, sodium hypochlorite, potassium permanganate, etc., so as to continuously generate the active constituents of fresh iron (III) / (II) (hydro) oxide, etc., and the heavy metals including As, Hg, Cd, Pb, Cr, Se, Sb, Cu, Zn etc. in the water body are removed quickly and effectively by way of adsorption, precipitation, redox, etc.</p> |
