Abstract :

Metallic powders have an important role in detectionand pollutant remediation from environment. Inthis way, iron nanoparticles has served as a newmaterial for environmental remediation. Thereforan economical solutions for many environmentalchallenges in the fields of pollutants elimination havebeen invented. Metallic oxide such as TiO2 in ananometric scale as a cheap material, have abilityfor using in photocatalytic process and remediation.In this article in addition of reviewing the propertiesof metallic and oxide nanoparticles in environmentalremediation process, remediation process by metalliciron nanoparticles was investigated and for instance,the remediation process of hexavalent chromium withthese nanoparticles have been illustrated.
