Abstract

Background and Objectives: Groundwater treatment by nano particles has received increasing interest in recent years. Chromium is a commonly identified contaminant in soils and groundwater.Zero-valent iron, as a natural redu tion agent can be used in controlling of contaminated sites. The aim of this research is investigation of HEXAVALENT CHROMIUM removal from AQUEOUS SOLUTIONs by using of IRON NANO PARTICLES the effective parameters.Materials and Methods: In this research the synthesized of the IRON NANO PARTICLES has performed by addition of NaBH4 to FeCl3 6H2O solution and Cr(VI) reduction efficiency in Batch system was studied. Also the impact of the important field parameters including pH, initial chromium concentration, nano zero valent iron concentration and retention time were investigated.Results: The results of this research showed that synthesized particles were in nano scale. In pH=3, chromium inlet concentration of 10 mg L-1, nano zero valent iron concentration 0.5 g L-1 and 2 minute retention time, 100% of Cr(VI) was removed.Conclusion: The concentration of nano zero valent iron had significant effect on the reduction of Cr(VI).The reaction occurred in a wide range of pH value and the reaction efficiency increased significantly with decreasing initial pH. The significant removal efficiency, high rate of process and short reaction time were showed that IRON NANO PARTICLES have significant potential in removal of Cr(VI) from contaminated water.
