  7. Abstract:
  8. One of the subjects that have been title for many research proposals in recent years is application of Nano Zero Valent Iron (NZVI) particles in contaminant removal from groundwater sources. Despite many studies being done, field application of this particles in a practical scale is not widespread yet which is due to many challenges like rapid settlement of particles or their unclear behavior through field application. The main purpose of this thesis in the first place is to find a practical and productive method for stabilization of particles and enhancement of their transport properties. To reach this goal, application of a natural polymer like starch has been studied as a solution. To evaluate the success of this method, series of nanolab experiments have been conducted on particles like X-Ray Differentiation (XRD), Scanning Electron Microscope (SEM) photography, Dynamic Light Scattering (DLS) and zeta-potential evaluation. Based on results of experiments mentioned above, synthesized particles contained zero-valent iron particles ranging 30 to 150 nanometer with high transportability. Then, particles were injected to a calibrated model to evaluate their performance in a media with properties like saturated soil and also to be able to compare results driven from injection with results collected from software modeling. This comparison proved that synthesized particles are highly transportable through saturated soil media
