摘要：
In the present work, nano scaled zero valent irons (nZVI) were synthesized in ethanol medium by the method of ferric iron reduction using sodium borohydride as a reducing agent under atmospheric conditions. The obtained iron nanoparticles are mainly in zero valent oxidation state and remain without significant oxidation for weeks. A systematic characterization of nZVI was performed using UV, XRD, SEM, TEM, PSA and BET studies. The obtained iron nanoparticles consist of a zero valent core surrounding a rest oxide shell. The diameter of iron nanoparticles was predominantly within the range 50-100 nm.
