Abstract:
Zero-valent iron nanoparticles are widely applicable for remediation of contaminated waters, surface water and wastewaters. There are many sites in UA and Europe, where these nanoparticles were tested or used for full scale remediation. The particles are produced either by milling of microscopic particles in aqueous or non-aqueous environment or by chemical reduction in gas atmosphere of hydrogen at high temperature. The particles are surface modified to improve their migration and reactivity. Besides knowing the particle application properties, the basic particle characteristics and features are unknown. This is due to their relatively rapid oxidation and by this change of surface properties. The goal of the paper is to make an overview of zero-valent iron nanoparticles and their composites preparation. Particle characterization by a wide spectrum of methods including TEM, SEM, BET, size distribution, Mossbauer spectroscopy, zeta potential etc. is also included.
