Abstract

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. The specific surface area of the iron nanoparticles is approximately 26m2/g and maximum benzen adsorption is 0.206mmol/g.
