    摘要: An aqueous iron suspension is disclosed, which comprises solid iron particles in the nanometer size range, which is prepared from ferrous-sulphate (FeSO
    4 ); copper-sulphate (CuS
    4 ), a reducing agent, and/or sodium-borohydride (NaBH
    4 ); sodium-hydroxide (NaOH); and optionally additives. Furthermore, a process is disclosed for the preparation of the iron suspension according to the invention, comprising the steps of forming of an aqueous solution comprising: a) aqueous ferrous-sulphate (FeSO
    4 ) or hydrated ferrous-sulphate (FeSO
    4 ×7H
    2 O); sodium-ditionite (Na
    2 S
    2 O); sodium-borohydride (NaBH
    4 ); sodium-hydroxide (NaOH) and hydrated copper-sulphate (CuSO
    4 ×5H
    2 O) starting materials; b) reaction of the reaction mixture according to step a) for 0,1-10 hours; and c) obtaining of the suspended product. Furthermore, the invention relates to the use of the iron suspension according to the invention for decontamination, preferably for the decontamination of soil, water, waste water or gas mixtures. Further, the invention relates to a device for the preparation of the iron suspension according to the invention.˙
