Abstract

In the present investigation colloidal silver nanoparticles was prepared by chemical reaction method from silver nitrate (AgNO3) and sodium citrate (Na3C6H5O7) in water. The preparation method were achieved at three levels of temperature (100, 150 and 200℃) the produced silver nanoparticles characterize by UV-vis Visible Spectroscopy, Scanning Electron Microscopy (SEM) and Particle Size analyzer the result of particle size analyzer show that their size distribution to lie in the range of (58.9 -202) nm. The results show that silver nanoparticles are 58.9, 76.4 and 202 nm at temperatures of (100, 150, 200) ℃, respectively can be produced.
