Abstract

Background and Objective: Drinking water supply is an important environmental challenge throughout the world. Water pollution with Nitrate is a serious human health hazard in Iran. The main purpose of this study is to evaluate the applicability of synthesized Zero-Valent Iron (ZVI) nanoparticles in removal of Nitrate from water empHasizing on the influence of pH variation on performance of nanoparticles. Method: ZVI nanoparticles were synthesized in the laboratory and measured for dimension with Transition Electron Microscopy (TEM) before using in the experiment. Impact of ZVI nanoparticles dosage on the removal of Nitrate from water was also examined in this study. Findings: Results indicated that performance of ZVI nanoparticles in the removal of Nitrate is greater in acidic environment compared to neutral and basic state. In addition, pH increased over the course of the experiment at initial acidic and neutral states. Discussion and Conclusion: Application of small amount of ZVI nanoparticles can reduce Nitrate content in water significantly. The principal fraction of removal reaction was achieved at initial stages due to acidic condition. Results of the present study showed application of small amounts of ZVI nanoparticles can reduce Nitrate concentration in waster scales significantly.
