Sažetak
Recent research has shown that nanoscale iron particles are effective material for the transformation of wide array of common environmental contamination in water systems. Zero valent iron nanoparticles (nZVI) are typically prepared by reducing Fe (II) of Fe (III) in an aqueous phase using sodium borohydride. In order to prepare nZVI of desired stability, a variety of stabilizing agents, surfactants or capping agents are employed in synthesis steps. The objective of this work is to provide comparison and quality control of iron nanoparticles produced under different experimental conditions. Therefore, the synthesis of nZVI from aqueous solution of iron salts after addition of different chelating ligands such as EDTA, dipicolinic and citric acid was studied. The resulting nanomaterials were characterized by scanning electron microscopy (SEM) which showed that the dendritic structure of nZVI in nano scale was favored in EDTA experiment. Preparation of nZVi was also tested by addition of selected heavy metals. Concentrations of metals in remaining aqueous solution were determined by inductively coupled plasma optical emission spectrometry (ICP-OES). The metal removal efficiency of nanoparticles was calculated from the observed changes in concentration.
