      Abstract:

      Nanoscale Zero Valent Iron (NZVI) particles have become a   material of interest due to their small size, large surface area,   and enhanced magnetic properties relative to their bulk   counterparts. Due to these properties, NZVI have become prevalent   in industrial, biomedical and environmental applications. The use   of NZVI in environmental remediation is of particular interest.   Large industrial areas containing underground storage tanks (UST)   are a cause of ground water and soil contamination from   chlorinated volatile organic compounds. Through the use of NZVI,   CVOC can be reduced to simple organic compounds that are easily   absorbed or digested through anaerobic processes. Considerations   for NZVI include size, charge, surface functionalization, cost   and efficiency. Methods for the synthesis and surface   functionalization of NZVI are examined as size and charge affect   mobility of the particles through the contaminated area during   remediation. Monitoring of the remediation is conducted through   pH testing and determination of electrochemical potentials as the   CVOC are reduced to less harmful organics.
