Kinetics and pathways for the debromination of polybrominated diphenyl ethers by bimetallic and nanoscale zerovalent iron: Effects of particle properties and catalyst
In this study, two kinds of commercially available nanoscale Fe0 slurries (NANOFER 25 and 25S), a freeze-dried laboratory-synthesized Fe0 nanoparticle (nZVI), and their palladized forms were used to investigate the effect of particle properties and catalyst on PBDE debromination kinetics and pathways. NANOFERs and their palladized forms were found to debrominate PBDEs effectively. The laboratory-synthesized Fe0 nanoparticles also debrominated PBDEs, but were slower due to deactivation by the freeze-drying and stabilization processes in the laboratory synthesis. An organic modifier, polyacrylic acid (PAA), bound on NANOFER 25S slowed PBDE debromination by a factor of three to four compared to NANOFER 25.

Measuring the reactivity of commercially available zero-valent iron nanoparticles used for environmental remediation with iopromide
Iopromide was rapidly dehalogenated by the investigated nZVI particles, following pseudo-first order reaction kinetics that was independent of the experimental conditions. The specific surface area normalized reaction rate constant (kSA) value in the batch reactors ranged between 0.12 and 0.53 L m−2 h−1; it was highest for the uncoated NANOFER 25 particles, followed by the polyacrylic acid-coated NANOFER 25S and air-stable NANOFER STAR particles. In the batch reactors all particles were less reactive in natural water than in synthetic water.
Distribution and Storage
Product availability: 500kg of slurry is usually dispatched in one day. Please consider using NANOFER STAR dry powder and preparation of fresh slurry by our dispersing unit in case you require larger quantities.

NANOFER slurry products are distributed in plastic canisters (capacity 5, 10 or 20 kg), small samples are available in PET bottles (100g, 250g, 500g). Storage in glass is not recommended due to pressure build-up.

Shelf-life: NANOFER slurry products are an extremely reactive dispersions of iron nanoparticles that – if in contact with oxygen or water – intensively oxidize. NZVI, which is capable of efficient reduction of contaminants in water, transforms into iron oxides and hydroxides. For this reason it is necessary to process the material as soon as possible, we do not recommend to store NZVI aqueous dispersions for a long time. If you need to do so, please store it in cold premises (5°C) in order to reduce corrosion rate. For more information, please read the article about nZVI slurry ageing in the download section.
