Abstract

Abstract

Background: One of the most important environmental pollutants that there is in sewage of different industrials is cyanide to cause pollution of water sources that are dangerous to humans and the environment. Cyanide can be removed in different ways from the aqueous media, but most of these methods are costly. Therefore, the aim of this study is the removal cyanide using iron nanoparticles.

Material and Methods: Removal of cyanide from aqueous media using iron nanoparticles in various conditions including the effect of the adsorbent, initial cyanide concentration, contact time and pH were studied in discontinuous phase. In this study, adsorption equilibrium and also the kinetics of the reaction examined.

Results: In the process of sharing discontinuous, the balance was achieved after 120 minutes of contact time and maximum amount of removal cyanide in the pH =11 for cyanide concentration of 2.5 mg/L and 1 gr of nanoparticle over 97% obtained. Also the results showed that the adsorption process fitted with Langmuir isotherm and chemical kinetic fitted with of secondary grade.

Conclusion: According to the findings, iron nanoparticles can be used as a suitable option for removal cyanide from aqueous solution in hazardous waste.
