NANO IRON s.r.o. products

New AIR-STABLE nZVI powder, consisting of Fe(0) surface stabilized nanoparticles. The product is easier and safer to store, transport, handle and process compared to non-stabilized nZVI NANOFER 25P but it still keeps extreme reactivity with reducible pollutants in water environment.

A novel aqueous dispersion of Fe(0) nanoparticles coated by inorganic sulphur-based structures. The product is extremly efficient in reduction of TCE while it keeps stable in water environment resulting in much better shelf life and longevity in comparision to standard products. The reactivity of NANOFER 25DS to chlorinated hydrocarbons is probably attributed to the higher hydrophobicity and conductivity of sulfide structures compared to iron oxides present on the surface of nanoparticles. The same structures inhibit corrosion of nanoparticles in water, improve resistance against fouling and passivation and result thus in higher longevity of nanoparticles.

Aqueous dispersion of Fe(0) nanoparticles with biodegradable organic surface modification, which has been designed especially for in-situ groundwater remediation. Frequent target contamination is hexavalent chromium and chlorinated hydrocarbons.

Reactive aqueous dispersion of Fe(0) nanoparticles without any organic or inorganic modification. The product exhibits an extremely high reactivity but is characterized by a higher degree of agglomeration and faster sedimentation.

It is possible to disperse NANOFER dry powder (25P or STAR) in various liquids in order to improve stability and migration, prevent agglomeration or adjust the reactivity of nanoparticles. Another intention might be a combination of nZVI and other compounds to create completly new products with unique features for alternative application. Please see few examples bellow.

Nanopowder, consisting of Fe(0) nanoparticles without surface modification, preserved in an inert nitrogen atmosphere. The product exhibits extremely high reactivity and is usable for secondary stabilization or modification depending on intended application.
