  7. Abstract:
  8. Recent advances suggest that many of the issues involving in improving water quality could be solved by using nano particles. Aquifer and groundwater remediation are also critical issues. Becoming more important as water supplies steadily decrease and demand continues to increase. Although some of the remediation technologies available today are , they are costly and time-consuming, especially pump and treat methods. A wide range of nano particles have been used for the removal of organic and inorganic contaminants. In the first part of this work, zero-valent Iron nano particles was synthesized and was covered with nickel as catalyst. Diameter of the synthesized nano particles was investigated using dynamic light scattering (DLS) experiments and transmission electron microscopy (TEM) and it was less than 100 nm.In the second part, Iron nano particles were used to dechlorinate and remove trichloroethylene from water in batch system. The effects of PH, temperature, nano particle loading and concentration of TCE on the rate of transformation were investigated
