Nanoparticle iron

Zero valent iron (ZVI) nanoparticles have been considered as effective materials for environmental remediation because of their strong reducing ability, high reaction activity, and excellent absorption properties. In this study, we synthesized iron nanoparticles using an environmentally friendly method in order to treat Cr(VI) ions in an aqueous medium.

In particular, the system undergoes three stages. At first stage the relaxation proceeds slowly so that the energy of system slightly decreases and the samples structure remains amorphous. Within second stage a structural transformation occurs which significantly changes PRDF and DCN for the relatively short time. The energy of the system is dropped considerably and the amorphous structure transforms into the crystalline. Finally, the crystalline sample undergoes the slow relaxation which reduces the energy of system and eliminates structural defects in crystal lattices.

In this article, iron nanoparticles were synthesized by reduction of FeCl3.6H2O 0,045M using NaBH4 0,25M. Characteristics of obtained iron particales were studied by Transmission Electron Microscopy (TEM), X-ray diffraction method (XRD) and BET specific surface area, and maximum benzen adsorption. The TEM results of synthesized iron nanoparticales show that iron particles are spherical in shape and connected in chains, the particale size is about 3 - 50nm. The X-ray results show that synthesized nanoparticles is iron at 44.720.
