  • Zero Valent Iron for Soil and Water Remediation

    Waterloo, Canada; Oberhausen, Germany. The Adventus Group, a multinational remediation technology enterprise, provides a review of the Observatory NANO Focus Report 2010 on the issues surrounding nano-scale ZVI (nZVI) for treatment of contaminated water and soil. The debate over nano-scale versus micro-scale zero valent iron (ZVI) has attracted the attention of leading scientists in the ...


  • All Zero Valent Iron are not Created Equally

    Particle size:  The particle size of ZVI is the primary and the most important aspects in choosing a type of ZVI.  The reductive dechlorination of chlorinated compounds is a surface area mediated reaction, meaning that in theory, the greater the surface area, the more reactive a ZVI particle is.  For ...
