Nanoparticles from a gold complex with sulfite ion as ligand: Preparation and characterization
Gold colloidal nanoparticles (GNPs) were prepared by reducing a complex of Au- Na3Au(SO3)(2) with sodium citrate. The procedure provides control of the dimension of nanoparticles produced, which is function of reaction time and concentration of reactants. The nanoparticles were separated by centrfigation and their characteristics and dimensions were studied using UV-Vis and IR spectroscopy and transmission electronic microscopy (TEM).
