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

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 .
