Green Synthesis of Charcoal Based Silver Nanoparticles - Characterization and Inorganic Arsenic Absorption Properties

Charcoal based Silver nanoparticles (C/AgNPs) have been prepared by reduction of Tollens reagent (ammonicalsilver nitrate, a complex of Ag+ ion) with biomolecule Dextrose under warmed conditions in the presence of ethanol treated charcoal. The C/AgNPs are characterized by Energy Dispersive Spectroscopy (EDS) and UV-Vis. spectroscopy. The morphological studies are carried out by SEM. Inorganic arsenic absorption properties have been studied by using 100ppm sodium arsenite solution. It has been observed that these C/AgNPs have good inorganic absorption properties.
