THE CHEMICAL METHODS OF SILVER NANOPARTICLES SYNTHESIS

Metallic nanoparticles are widely used in many industries due to their unusual properties, which are dependent on the nanometric sizes. Recently, attention has been focused around the silver nanoparticles, which beside unusual optical, electronic and chemical features also exhibit remarkable antimicrobial properties. There are many methods of metallic nanoparticles synthesis, however the most widespread are chemical methods which require the use of suitably selected reducing agents and stabilizers. This article involves an overview of selected methods silver nanoparticles synthesis. Moreover the work was carried out the synthesis of silver nanoparticles by chemical reduction using silver nitrate as a source of silver ions, trisodium citrate as a reducing agent and polimer stabilizer. Nanosilver particles were characterized by AAS method (Atomic Absorption Spectrometry). The optical properties of nanosilver in water solution were studied through UV-Vis spectroscopy.
