1st International Symposium on Nanoscience and Nanomaterials
Keywords: Biosynthesis, Water hyacinth, Metal nanoparticles, Transmission Electron Microscopy
Green-chemistry methods are becoming more important nowadays; particularly the use of bioreduction
to produce metal nanoparticles is well established as a significant contribution to develop clusters
and one-dimensional nanostructures. The utilization of this method is part of a self-sustained technology
where the biomass source is water hyacinth (Eichhornia crassipes), a plant that is considered a pest. This
research presents the results of biosynthesis by dried biomass of water hyacinth in aqueous solutions of
MnSO4, K2Cr2O7, FeCl3, CoCl2 and Ag standard solution, precursors of Mn2+, Cr3+, 2+, Fe3+, 2+ Co3+,
2+ and Ag+ ions on scale size of quantum confinement (
