Metallic iron for environmental remediation: the long walk to evidence

The science of metallic iron for environmental remediation is yet to be established. The prevailing theory of the Fe-0/H2O system is characterized by its inability to fully rationalize the concept that holds up the technology. The present article demonstrates that Fe-0 technology was introduced by altering the course of mainstream science and by distorting the work of corrosion scientists. The Fe-0 research community is now facing the consequences of this initial forcing. The technology is still innovative despite two decades of commercialization.
