Preparation and study of the structural and optical properties of silver nanoparticles prepared from extracts of some plants

Abstract

The study included  the preparation of silver nanoparticals using Punica  granatum extract . as  silver  nanoparticals  were  prepared by  biological method . which is one of the best ways for its  cheapness and the fact  that is does not require time and does  not  leave  toxic substance .in the  study , the  active  compounds of the  extract  were  detected and some  physical   properties of  AgNps  were studied . the  optical and  structural  properties  of  the prepared  nanoparticles  were  studied  by Uv-Visible spectrophoto meter measurement. perform an infrared  spectrophotometric  test (FTIR ) a filed – emitting  scanning  electron   microscope  was   also  performed , ( EDX ) , ( X-RAY ) and  the  results of ( FESEM ) measurement showed that  silver  nanoparticles are of oval shape , and of different sizes ranging from ( 32.55 -70.55 ) nm . with  a rate of  (45.98) nm .
