ABSTRACT


Silver nanoparticles find applications in catalysis, optics, electronics and other areas due to their
unique size-dependent optical, electrical and magnetic properties. Recently, most of the applications of silver nanoparticles are in antibacterial/antifungal agents in biotechnology and bioengineering, textile engineering, water, and silver-based consumer products. Silver nanoparticles have been incorporated into a wide range of medical devices, including but not limited to cement, surgical instruments, surgical masks and wound dressings. Silver nanoparticles have been prepared by electrolysis method using silver as anode and graphite as cathode in presence of a reducing agent sodium potassium tartrate (SPT) , in the absence and presence of a capping agent polyvinyl alcohol. The silver nano particles synthesised have been characterized by uv- visible absorption spectroscopy, fluorescence spectroscopy, SEM and EDAX. The particle size has also been determined. Since electrochemical method is used , the reaction can be started and stopped at any time. So this method is considered as green method. There is no use of toxic chemicals. Water is used as solvent.


Keywords: silver nano particles, uv-fluorescence, SEM, EDAX, Electrochemical method , sodium potassium tartrate
