Abstract

Introduction: In many studies, nanoparticles was used to remediation of HEAVY METALS from WATER, results of these study showed that these materials have high power in contaminant remediation from aqueous solutions, and bio-absorbents also have high power in WATER infiltration. The main purpose of this paper is investigation of effects of adding of iron oxides nanoparticles to CHROME removal bio-filters.Methods: used method in this study was filtration, also studied variable was absorbent type. Indeed, effect of absorbent type on percent of HEAVY METALS remediation was studied. In two first steps contaminated WATER with three concentrations (883.7, 1767.4, and 8837 ppm) was remediated with using of soil and sawdust absorbents. In two next steps, for comparison, some IRON OXIDE NANOPARTICLES with several herbaceous absorbents were adding to soil and sawdust absorbents and again absorption was performed.Results: results showed that best absorbent is soil absorbent and IRON OXIDE NANOPARTICLES, with maximum removal percent equal to 96.2%. Also best turnover was obtained from 8837 ppm of primary concentration of heavy metal. In other hand, in other experiments that used from IRON OXIDE NANOPARTICLES, adding of nanoparticles caused to increase in CHROME absorption and conversion of Cr6+ to Cr3+.Conclusion: with use of the results of this study can be said that Combining of IRON OXIDE NANOPARTICLES with CHROME removal filters can be convert Cr6+ to Cr3+, and process turnover will increased.
