The effectiveness of the reactive properties of zero-valent iron nanoparticles (nZVI) increases by the application of a direct current (DC). The saving of reactive agent and prolongation of the longevity of nanoparticles in the subsurface are the main advantages of DC application, which render in-situ chemical reduction by nZVI considerably more economical. During the support of nZVI remediation by an electric current, the synergic effect of the electric current close to the cathode is expected. There is a subsidy of electrons and production of H+ during the process. nZVI is protected against oxidation and has a higher reactivity with the contaminants.Keywords: Iron particles, reduction, reactive column, electric current
