Synthesis and Characterization of Silver Nanoparticle by Chemical Route Method

N Senthilkumar, S Sakthi Raadha, S Udhayavani

Abstract


Nanoparticles being the smallest unit, ranging between 1 to 100 nm in size play an important role in various fields and show distinct physical, chemical and biological properties from their bulk counterparts due to higher surface volume. In this work, silver Nanoparticles were synthesized by Sonication method through vibration and elevated temperature, in which silver nitrate as a metal precursor and sodium citrate as a reducing agent were used. The synthesized silver Nanoparticles were characterized by UV-visible spectroscopy and Scanning Electron Microscopy (SEM). The liquid solution containing nanoparticles were used for UV visible spectroscopy which revealed the formation of silver Nanoparticles by exhibiting the typical surface Plasmon absorption. The formation of silver nanoparticles was observed with maxima at 418–447 nm from the UV-Vis spectrum. Silver nanoparticles in powder form were used to take SEM image to study the morphological features of nanoparticles as well as it also gives the size of the nanoparticles to check whether the synthesized nanoparticles are within the Nano scale range. Observations from SEM image reveal that the nanoparticles obtained by chemical route technique are in the range between 75–90 nm.
