NANOFER 25P is available primary for large-scale projects as a feedstock for preparation of a water slurry product, which can be easily manufactured by our industrial dispersion unit.
The product requires special certified packaging and processing under protective atmosphere by reason of its pyrophoric properties. We recommend to use our air-stable NZVI powder NANOFER STAR if you consider pyrophoricity as problematic attribute.

Full-scale application of nZVI: mixed contamination of chromium and chlorinated solvents
Application of surface stabilized iron nanoparticles (NANOFER 25S) to eliminate groundwater contamination of chlorinated hydrocarbons (CHCs) and hexavalent chromium (Cr6+) at KARA Trutnov site in the Czech Republic.
Zero-Valent Iron Nanoparticles
Pilot Injection of Nanoscale Zero-Valent Iron - Kara Trutnov site (CZ)
Groundwater contamination at the KARA site is caused mainly by obsolete technological practices and irresponsible handling of chlorinated ethylene and chromium compounds during processing of fur in past. Injection of nZVI has been proposed to finalize the treatment of the site.

Zero-Valent Iron Nanoparticles Reduce Arsenites and Arsenates to As(0) Firmly Embedded in Core−Shell Superstructure: Challenging Strategy of Arsenic Treatment under Anoxic Conditions
Here, we introduce a groundbreaking method involving the use of oxidic-shell- free nanoscale zero-valent iron (OSF-nZVI) to treat arsenite/arsenate-polluted underground water. Under anoxic conditions, OSF-nZVI is capable to reduce As(III)/As(V) species to As(0) (up to 65% of total arsenic content). Thus, reduction synergistically contributes to sorption tuning suitably the chemical nature and isoelectric points of As species, thereby enhancing arsenic removal from an anoxic aqueous environment. More importantly, As species are locked between the Fe(0) core and iron(III) oxide outer shell.
Distribution and Storage
Product availability: The product is available in order of tones in our stock for immediate delivery.

NANOFER 25P is distributed in special, gastight deposit containers. It is recommended to use our industrial dispersion unit to process this nanopowder into a slurry form. Another option is to use a glovebox or simmilar device, where pyrophoric substances can be safely manipulated under an innert atmosphere.

Shelf-life: NANOFER 25P may be stored for unlimited time in the original packaging. Please avoid contact with water and excesive heat before use. The gas pressure must be checked every 6 months and adjusted if necessary.

Shipping: The product is transportable via road (ADR), rail (RID) or sea (IMDG) according to international standards for shipping of dangerous goods. It is not possible to deliver pyrophoric substances by plane (IATA).
