In respect to research and testing of our product, we would like to inform you that we have finished evaluation of nZVI slurry ageing behaviour. The example of Fe⁰ reactive nanoparticles (water slurry product) ageing is presented in following chart showing the degradation of NANOFER 25S depending on time and storage conditions. Please read the full article here.

All measurements were made through the use of nZVI TESTER, which principle is based on measuring of developing hydrogen volume during the reaction of Fe(0) with acid. This "Hydrogen method" was compared to Mössbauer spectroscopy and X-ray powder diffraction [thanks to Prof. Radek Zbořil, Ph.D.; Regional Centre of Advanced Technologies and Materials (RCPTM)].
