|Title:||SYNTHESIS OF SILVER NANOPARTICLE VIA SOLVENT EXTRACTION ROUTE|
SOLVENT EXTRACTION ROUTE
|Abstract:||Stable organic fluid containing silver nanoparticles have been prepared by the extraction — reduction method. Silver nitrate was extracted in n-Hexane or Toluene using different extractants namely Cyanex 923, Cyanex 471X and Aliquat 336. The Ag- extractant complex was reduced with sodium borohydride to get organic fluid containing silver nanoparticles. The obtained silver nanoparticles were stable and silver nanoparticles did not precipitate at room temperature. The molarity of AgNO3, HNO3 and extractants was varied to investigate the effect of variation on particle size, but no significant effect was observed. The silver nanoparticles were separated from the organic fluid and characterized by FTIR, XRD, FESEM, AFM & TEM. Results indicate that silver nanoparticles are in the range of 20 to 70 rim and are well modified by the extractants..|
