NANOFER 25S: nZVI slurry for groundwater remediation

Aqueous dispersion of Fe(0) nanoparticles with special surface modification which is based on combination of a biodegradable organic and inorganic stabilizer. Due to the narrow size distribution of nanoparticles and sophisticated stabilization process, the product exhibits a high reactivity with a large scale of pollutants and very low degree of agglomeration, which implies for excellent migration and sedimentation properties. It is designed especially for the application in the reduction technology of groundwater remediation.

Please follow the instructions for Distribution and Storage.
